Frequently asked questions

Use CSV table data or a JSON array as expected by this page. If validation fails, try a smaller sample and check encoding, separators, file type, or expression syntax.

The usual causes are input format issues, browser support, or option settings. Verify the workflow with the sample first, then replace it with your own data.

You can copy ordinary results, but review critical fields and edge cases before production use, official submission, financial calculation, or publication.
