CSV Data Source
This type of data source belongs to the Files category in the data source library. It is used to retrieve static data from CSV files (Comma-Separated Values, text format) located on the local server.
Once the file is uploaded, you should define its configuration. In particular, you should specify the column separator used to divide each row into columns.
Notes
see General remarks on data sources
- The data from the data source is not automatically refreshed. The app administrator must upload the CSV file again to update the data.
- If data changes on a regular basis, then you should use an Online CSV dynamic data source.
Example
ExampleCSVFile
You want to retrieve from a CSV file the number of incidents and requests per employee by department:
- The file contains a header row ==> the First Line Contains Column Titles property is checked
- Column separator = ; (semicolon)

- Data in static data sources comes from the last file upload.
- Data in dynamic data sources is refreshed when you open the app in edit mode.
AutoRefresh
Auto Refresh (Note: Only for dynamic data sources): Used to indicate the automatic refreshment interval for data from the data source in hours/minutes.
- Data is automatically refreshed each time the app is run and each time the page is redisplayed, regardless of whether it is in execute mode or edit mode.
- Caution: The updating of data requires additional activity on the Service Apps platform.
- You should define an automatic refreshment interval only if the app is required to constantly display real-time data for long periods of time on screen.
example View dashboard data
- You should not specify an automatic refreshment interval if the app is only used for displaying a snapshot of data.
example Display a portal where catalogs can be consulted

example CSV file row = Incident per Employee, "2,7" (column separator = comma)
- Text delimiter = double quotes ==> The row is divided into 2 columns: Incident per Employee; 2,7
- Text delimiter = unspecified ==> The row is divided into 3 columns: Incident per Employee; "2 ; 7"
