When trying to upload a CSV file as a data source for the dataset, you get the Failed to upload file message or the ERR.FILE.PARSE_FAILED error.

1. Check your CSV file encoding: we support UTF-8, UTF-16, Windows-1251, and UTF-8-sig.

2. Check that column separators are correct and in place throughout the file. The available values are a comma (,), semicolon (;), and tab character.

3. Try uploading the file again by following these steps:

   • Disable ad blockers in your browser.
   • Go to the DataLens dataset page in incognito mode.
   • Use a different browser.
