How to use this tool
- Paste comma-separated data with unique header names.
- Convert and review the JSON array.
- Download or copy the result.
How it works
Each data row becomes an object. Values remain strings, preserving identifiers such as 00123 and avoiding unexpected date or number conversions. Quoted fields may contain commas, line breaks and doubled quotation marks.
What to check before using the result
Input must use commas, not tabs or semicolons. Duplicate or empty headers and inconsistent field counts produce errors instead of overwriting values. Completely blank data lines are skipped.
BEFORE YOU GO
Your work stays yours.
Are my files, text or numbers uploaded?
No. This tool processes the input in your browser tab. It does not send your input to our servers. Leaving or refreshing the page clears the working input.
Do I need an account or subscription?
No account is required for this public tool. You can complete the task and download the result directly. An account is useful when you want to measure visits to your own website or manage tracked campaign links.
Can I share or link to this tool?
Yes. Use the tool link below in a tutorial, team resource list or campaign checklist. The link opens an empty tool; your private input is not included.
