- Import tasks from file
All example below use Windows Terminal/PowerShell.
Import tasks from file
Task definitions can be read from CSV or Excel files.
The options are as follows:
.\ctrl-q.exe task-import --help
Usage: ctrl-q task-import [options]
create tasks based on definitions in a file on disk, optionally also importing apps from QVF files.
Options:
--log-level <level> log level (choices: "error", "warn", "info", "verbose", "debug", "silly", default: "info")
--host <host> Qlik Sense server IP/FQDN
--port <port> Qlik Sense repository service (QRS) port (usually 4242 for cert auth, 443 for jwt auth) (default: "4242")
--schema-version <string> Qlik Sense engine schema version (default: "12.612.0")
--virtual-proxy <prefix> Qlik Sense virtual proxy prefix (default: "")
--secure <true|false> https connection to Qlik Sense must use correct certificate. Invalid certificates will result in rejected/failed connection. (default: true)
--auth-user-dir <directory> user directory for user to connect with
--auth-user-id <userid> user ID for user to connect with
-a, --auth-type <type> authentication type (choices: "cert", "jwt", default: "cert")
--auth-cert-file <file> Qlik Sense certificate file (exported from QMC) (default: "./cert/client.pem")
--auth-cert-key-file <file> Qlik Sense certificate key file (exported from QMC) (default: "./cert/client_key.pem")
--auth-root-cert-file <file> Qlik Sense root certificate file (exported from QMC) (default: "./cert/root.pem")
--auth-jwt <jwt> JSON Web Token (JWT) to use for authentication with Qlik Sense server
-t, --file-type <type> source file type (choices: "excel", "csv", default: "excel")
--file-name <filename> file containing task definitions
--sheet-name <name> name of Excel sheet where task info is found
--update-mode <mode> create new or update existing tasks (choices: "create", default: "create")
--limit-import-count <number> import at most x number of tasks from the source file. Defaults to 0 = no limit (default: 0)
--sleep-app-upload <milliseconds> Wait this long before continuing after each app has been uploaded to Sense. Defaults to 1000 = 1 second (default: 1000)
--import-app import Sense app QVFs from specified directory
--import-app-sheet-name <name> name of Excel sheet where app definitions are found
--dry-run do a dry run, i.e. do not create any reload tasks - just show what would be done
-h, --help display help for command
The options are almost the same irrespective of source file type:
The --sheet-name is only used/valid/relevant when --file-type is set to excel.
Why? Because there are no sheets/tabs in CSV files.
Source file columns for task defintions
The source file format is quite relaxed, but a few rules apply:
- The first column in the source file must be the task number.
- This value uniquely identifies each task that should be imported and should be incremented by one for each task.
- If this first column is empty the whole row will be ignored.
- All other columns, mandatory and optional, beyond the first one may be placed in any order.
- For mandatory columns the names listed below must be used (but they can be placed in any order in the file, except the first column).
- All mandatory columns must be present in the source file, even if they are not used/empty. For example, there may not be any tasks with schema/scheduled triggers, but the schema trigger columns must still be present in the source file.
- “Counter” columns are used to indicate that rows in the file are associated.
- All rows involved in defining a certain task have the same “Task counter” value.
- All rows involved in defining a certain schema or composite event have the same “Event counter” value.
- All rows involved in defining a certain composite event rule have the same “Rule counter” value.
- The file format used when exporting task tables to disk is a superset of the format used for task import. It’s thus a good idea to first do a task export, look at the file format and then adopt as needed before importing.
The mandatory columns in the task definition file are:
| Column name | Comment | Description | Valid values |
|---|---|---|---|
| Task counter | 1 | Counter starting at 1. Increments one step for each task. All rows associated with a specific task should have the same value in this column. | Integer > 0 |
| Task type | 1 | Type of task. In the future Ctrl-Q may support more task types. | Reload / External program |
| Task name | 1 | Name of the task that will be created. | Any string. Emojis allowed 🤪. |
| Task id | 1 | When creating new tasks a new task ID will always be created. This column is instead used to create task chains: it links a composite trigger in a downstream task with an upstream task via this column’s value. | Any string, but to make it easier to verify task chains it’s recommended to use integers or an easy to understand format in this column. For example “3” or “new-task-3”. If no downstream task will link to the task being defined, this column can be left empty. |
| Task enabled | 1 | Should the created task be enabled or not. | 1 / 0 / blank. 1=enabled, 0 or blank=disabled |
| Task timeout | 1 | Timeout for the created task, i.e. number of seconds the task is allowed to run before it’s aborted. | Seconds |
| Task retries | 1 | Number of retries to make if the task execution fails. | Integer >= 0 |
| App id | 1 | The Sense app the task should be associated with. | If a valid GUID is specified it’s assumed to be an app id. The task will be associated with that app. If the app id starts with newapp- it is a reference to an app that is imported during the current Ctrl-Q execution. The integer following newapp- is the value in the App counter column in the Excel definitions file. |
| Partial reload | 1 | Should the task do a partial or full reload of the app? | 1 / 0 / blank. 1=true, 0 or blank=false |
| Manually triggered | 1 | Is the task manually triggered or not? | 1 / 0 / blank. 1=true, 0 or blank=false |
| Tags | 1 | Tags to set on the created task. | Format is “tag1 / tag2 / tag with spaces in it”, i.e. separate tag names by “space-forward slash-space”. |
| Custom properties | 1 | Custom properties to set on the created task. | Format is “CustPropName1=Value1 / CustPropName2=Value2” |
| Event counter | 2 | Counter identifying events associated with the task defined in the previous line. One task can have zero or more events associated with it. | Integer > 0 |
| Event type | 2 | Which event type does this line specify? Schema events deal with time-based execution of the task. Composite events are used to build task chains. | Schema / Composite |
| Event name | 2 | Name of the event. | Any string |
| Event enabled | 2 | Is event enabled. | 1 / 0 / blank. 1=enabled, 0 or blank=disabled |
| Schema increment option | 3 | Type of schema event. For reference only, not used when Sense evaluates schema events. | once / hourly / daily / weekly / monthly / custom |
| Schema increment description | 3 | Structured description of the schema increment option. For reference only, not used when Sense evaluates schema events. | Integers separated by space, e.g. “0 0 1 0” for weekly |
| Daylight savings time | 3 | Control how the schema event should deal with dayligt savings time. | ObserveDaylightSavingTime / PermanentStandardTime / PermanentDaylightSavingTime |
| Schema start | 3 | First valid time for the schema event. The event will not fire before this moment. | A valid timestamp string, e.g. 2022-10-19T10:19:30.000 |
| Schema expiration | 3 | Last valid time for the schema event. The event will not fire after this moment. | A valid timestamp string or 9999-01-01T00:00:00.000 to signify “never” |
| Schema filter description | 3 | Used to control when a schema event is allower to trigger. More info here. | Default: “* _ - _ * * *” |
| Schema time zone | 3 | Time zone the schema event is evaluated in | E.g. “Europe/Paris” |
| Time contstraint seconds | 4 | Used for composite events. Defines a window in which all dependent tasks have to complete. | Integer >= 0 |
| Time contstraint minutes | 4 | Used for composite events. Defines a window in which all dependent tasks have to complete. | Integer >= 0 |
| Time contstraint hours | 4 | Used for composite events. Defines a window in which all dependent tasks have to complete. | Integer >= 0 |
| Time contstraint days | 4 | Used for composite events. Defines a window in which all dependent tasks have to complete. | Integer >= 0 |
| Rule counter | 4 | Counter identifying rules that define upstream task executions the current task is depending on. | Integer > 0 |
| Rule state | 4 | Is the rule waiting for success or failure of upstream task? | TaskSuccessful / TaskFail |
| Rule task name | Name of the rule | Any string | |
| Rule task id | 4 | Reference to the upstream task. | Any string (if referring to a task within the same file), or a valid id of a task that already exists in Sense. Two options exist: If the “Rule task id” has the same value as the “Task id” of another task in the source file, those two tasks will be linked via this rule. If the “Rule task id” refers to an existing task id in Sense, the new rule will link to that existing task. |
Meaning of “Comment” column above:
1: These columns are required for all lines where top-level task information is defined.
2: These columns are required for all lines where general event info (shared for schema and composite events) is defined. There may be zero or more such lines for a specific task.
3: These columns are required for all lines where schema events info are defined.
4: These columns are required for all lines where composite events (“task chains”) are defined.
💡 Tip
Example task definition files are available on this page.Source file columns for app import definitions
If apps should be imported (by means of the --import-app option) an Excel file must be provided with info about what app QVF files should be imported, as well as details about each app import.
A sheet name (where the app details are found) in the Excel file must also be specified using the --import-app-sheet-name option.
The columns (case sensitive!) in the app import definition file are:
| Column name | Description | Valid values |
|---|---|---|
| App counter | Counter starting at 1. Increments one step for each app. | Integer > 0 |
| App name | Name of the app that will be created based on the specified QVF file. | Any string. Emojis allowed. |
| QVF directory | Directory where app QVF files are stored | Any valid path, absolute or relative. |
| QVF name | Name of QVD file, including extension. | Any valid file name. |
| Exclude data connections | Should data connections stored in the QVF file be excluded during app import or not. | true / false |
| App tags | Tags to set on the imported app. | Format is “tag1 / tag2 / tag with spaces in it”, i.e. separate tag names by “space-forward slash-space”. |
| App custom properties | Custom properties to set on the imported app. | Format is “CustPropName1=Value1 / CustPropName2=Value2” |
| Owner user directory | If app owner should be set for this app, specify the user directory name here. Both user directory and user id must be correctly defined for the app owner to be updated. | Any user directory currently defined in the QMC, or Internal for Sense internal accounts. |
| Owner user id | If app owner should be set for this app, specify the user id here. Both user directory and user id must be correctly defined for the app owner to be updated. | Any user ID defined in the user directory defined in Owner user directory column (above). |
| Publish to stream | If this app should be published, specify stream id or name here. If the id is not associated with a stream or the specified stream name does not exist the app will not be published | Any existing stream name or id associated with an existing stream. |
| Publish options (optional) |
Specify publish options here, for example if an already published app with the same name should be overwritten or not. The default behaviour is publish-replace, which will be used when no “Publish options” column is present in the Excel sheet or that column exists but is empty. |
publish-replace: If there already exists a published app with the same name in the specified stream, replace that app with the new one. publish-another: If there already exists a published app with the same name in the specified stream, publish tnother one. delete-publish: First delete an already existing app (if there is one), then publish the new app. |
The publish options are described in more detail here.
Example: Export tasks to CSV, then import tasks from same CSV
This example will
- Export ca 50 tasks to a CSV file
- Import tasks from the just created CSV file
The CSV file created during the task export will contain some columns that are not needed during task import (last execution timestamp for each task and similar).
That’s fine though, during the task import Ctrl-Q will only look at the required columns and simply disregard all other columns.
Export tasks to CSV file:
.\ctrl-q.exe task-get `
--auth-type cert `
--host pro2-win1.lab.ptarmiganlabs.net `
--auth-user-dir LAB `
--auth-user-id goran `
--output-format table `
--output-dest file `
--output-file-name tasks.csv `
--output-file-format csv

Now let’s import tasks from the tasks.csv file:
.\ctrl-q.exe task-import `
--auth-type cert `
--host pro2-win1.lab.ptarmiganlabs.net `
--auth-cert-file ./cert/client.pem `
--auth-cert-key-file ./cert/client_key.pem `
--auth-user-dir LAB `
--auth-user-id goran `
--file-type csv `
--file-name tasks.csv
It’s worth noting that all the created tasks will be linked into the task chains that existed when the tasks where first exported into the CSV file.
This happens because the composite event rules that were exported into the CSV file (i.e. “start the task when task A and task B have successfully finished reloaded”) contain task IDs that point to already existing reload tasks in Sense.
When that’s the case the newly created tasks (based on the info in the CSV file) will link to those existing tasks.
This way a newly created task (based on info in the CSV file) can still be configured to start after some already existing task finish reloading.
Note how Ctrl-Q first creates the reload tasks and any associated schedule triggers in a first step, then add any composite triggers in the second step.
This is needed as a composite trigger may refer to an already existing and/or a newly created task (or multiple tasks of course), i.e. all tasks must first be created. Only then is it possible to create composite triggers.

Example: Import apps from QVF files and create associated reload tasks
This example will
- Import 3 apps from QVF files. Definitions of which files to import are stored in an Excel file.
- Tags and custom properties will be set for the apps.
- New app owners will be set.
- The apps will be published to streams.
- Create reload tasks based on definitions in same Excel file (but on a different sheet).
- The reload tasks will be associated with the previously imported apps.
- The reload tasks will be linked in a task chain.
- Some imported tasks will be triggered by already existing Sense tasks while others will be triggered by newly created tasks.
- There will be a 2 second delay after each QVF file has finished uploading, to reduce load on the Sense server.
The task import command looks like this in PowerShell:
.\ctrl-q.exe task-import `
--auth-type cert `
--host pro2-win1.lab.ptarmiganlabs.net `
--auth-cert-file ./cert/client.pem `
--auth-cert-key-file ./cert/client_key.pem `
--auth-user-dir LAB `
--auth-user-id goran `
--file-type excel `
--file-name tasks.xlsx `
--sheet-name "Ctrl-Q task import 1" `
--import-app `
--import-app-sheet-name "App import" `
--sleep-app-upload 2000
Some comments about the above command:
- The certificates used to authenticate with Sense are stored in the
certsubdirectory, right under where Ctrl-Q is started from.
That’s the default locataion, meaning that the options--auth-cert-fileand--auth-cert-key-fileare really not needed in this example. - The app and task definitions are found in a Excel file (
--file-typeoption) namedtasks.xlsx. - Task definitions are found in the Excel file’s sheet named
Ctrl-Q task import. - The
--import-apptells Ctrl-Q to import certain apps before tasks defined in theCtrl-Q task import 1sheet are created. This parameter is optional. If it is not included no apps will be imported. - The
--import-app-sheet-nametells Ctrl-Q that a list of apps to be imported (and import parameters for each app) is found theApp importsheet of the Excel file.
NOTE 1: A sample defintions Excel file is available in the GitHub repository. NOTE 2: The structure of the Excel sheet specified by the

Defining tasks to be created
The format is the same as when importing tasks only (and no apps).
More info here.
Associating new tasks with imported and existing apps
A few special cases apply when tasks are created and apps also imported.
In this situation it’s important that tasks can be associated with either the newly imported apps or already existing apps.
Similarly, for composite task triggers (used to create task chains) it’s important that either newly created tasks or already existing tasks can be referenced.
Let’s say the following three QVF files should be imported into Sense.
Note the App counter column, with values 1, 2 and 3.
Now let’s look at the tasks to be created.
In the image below the main info (task name etc) for each of the four tasks is shown.
Note that the Task id column has both proper GUIDs and simple integers in it.
This will be important when defining composite triggers.
Finally let’s look at the composite triggers associated with the last of the four tasks.
That composite trigger relies on two tasks, one that should fail (TaskFail) to trigger the composite trigger and one that should succeed (TaskSuccessful).
The important part here is the last column, Rule task id:
- If that column contains a valid GUID it is assumed to be a reference to an existing task.
- If the column contains an integer it is assumed to be a reference to a newly created task.
Which task? The one with the same integer number in theTask idcolumn (see previous paragraph).
This way it’s possible to chain new reload tasks to both already existing tasks and new ones.
