Developer workflow

Turn a spreadsheet into an API payload

CRM and analytics exports often arrive as CSV while APIs expect JSON arrays. This workflow lets you inspect the table, convert rows to objects, pretty-print the result, and validate before you POST.

When to use this workflow

  • Column names need a quick visual check before conversion.
  • You want to catch malformed JSON after a manual edit.

Tips

Tips for better results

  • Normalize header names in the spreadsheet first when APIs expect camelCase keys.
  • For very large files, convert a sample slice first to verify shape.
  • Follow with JSON Compare if you are migrating from a previous import format.

FAQ

Frequently asked questions

Are my spreadsheet rows uploaded?

Conversion runs in your browser. Utilnivo does not store CSV or JSON contents.

What about Excel .xlsx files?

Export or save as CSV first, then run this workflow. For PDF tables, use PDF to Excel separately.

Can I go the other direction?

Yes. Use JSON to CSV when you need a spreadsheet-friendly export from an API response.
