You can upload .csv and .sav files to Crunch. If you have a different type of data you can import it using the R or Python client libraries. Please contact us if you're having trouble getting your data into Crunch and we can help import it.
To import data using the Crunch app, click the top menu and select New Dataset from the dropdown, and then select your file format. Select a file on your computer or enter a url for the file to be uploaded.
