When this feature is enabled, any user can upload a CSV file to analyze in Sigma. The data from the file is written back to the organization's data warehouse and can be joined to other data stored in that warehouse. An admin must set up write access to the data warehouse to have this feature enabled.
When uploading a CSV, Sigma lets you select the delimiter, quote character, and escape character. You have a preview of how the data will display in Sigma to help guide your choices.
When a CSV is uploaded via Sigma, Sigma creates a table in the database. This table is only accessible in Sigma through the worksheet created by the CSV upload. To share a data in a CSV file, the user needs to share the Sigma worksheet. Other users cannot access the table directly in the database through Sigma.
If there are no longer worksheets referencing a table that was created by CSV upload, that table will be removed from the data warehouse within 24 hours, during scheduled clean up jobs.
