Load CSV files in Free Trial

In ThoughtSpot’s free trial, you can upload your own data to perform live queries on it. You can connect to your cloud data warehouse, and you can upload 10 flat data files, or CSV files. The file size limit is 50 MB.

Your data should be in a CSV (comma separated values) file before you load it. A CSV file is a text file made up of data fields separated by a delimiter and optionally enclosed with an enclosing character.

This feature is exclusive to ThoughtSpot Free Trial. Use Connections to access your data in ThoughtSpot Cloud.

CSV file formatting

A CSV file contains a delimiter that marks the separation between fields in the data. The delimiter is usually a comma, but it can be any character. The file also contains fields optionally enclosed with double quotes. Use these guidelines when creating the CSV file:

  • As a best practice, use a | (pipe) or tab as the delimiter, because those characters are less likely to occur within the data values.

  • When a field contains the delimiter, the field must be enclosed in double quotes.

ThoughtSpot supports a wide range of date and timestamp formats in the CSV file. See Date and time formats reference. Blank values in user-uploaded CSV files are interpreted as NULL values. These include the values (case-insensitive):

  • NULL

  • \N

  • NA

  • N/A

  • [space]

If you are appending data to an existing schema or table, columns in the CSV file must be in the same order as defined in the target table.
