# Uploading CSV Files
Arcwise lets users upload CSV and TSV files. These files can then be joined with other data from your data warehouse or other connected tools (Salesforce, Netsuite, etc.).
Uploading data as a CSV through Arcwise also makes it easier to work with via AI and makes the AI more effective on that data.
Currently, only files up to 1GB are supported, although this limit can be increased by reaching our directly to your Arcwise administrator or the Arcwise team.

If your data is large the data in the sheet will be truncated to 100 rows. You can still work with this data, however! See [working-with-large-data](https://docs.arcwise.app/using-arcwise-in-sheets/working-with-large-data "mention").
