Issue descriptionIssue description

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

SolutionSolution

  1. Check the encoding of data in your CSV file. Currently, we support UTF-8, UTF-16, Windows-1251, and UTF-8-sig encodings.

  2. Check the correctness of column separators in the file (as well as their presence throughout the content from beginning to end). At the moment, we support comma, semicolon, and tab as column separators.

  3. Try uploading the file again by doing the following:

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

If the issue persistsIf the issue persists

If the above recommendations did not help solve the issue, create a request for technical support.
In the request, specify the following information:

  1. Link to the problematic dataset
  2. HAR-file built when attempting to add a joined table to the dataset
  3. CSV file that you are trying to upload to the dataset as a data source.

Alert

Before sending the CSV file to technical support, do not forget to clean it of sensitive content
