How to use this tool
Paste a JSON array of objects or rows. Review the generated CSV table, change whether object headers appear and download the result. Quotes, commas and line breaks are escaped automatically.
Quick steps
- Paste a JSON array of flat objects or equal-length value arrays.
- Review your escaped CSV output and choose whether to include column headers.
- Copy or download the CSV for use with other applications.
Practical tip
Only flat objects are supported. Nested objects and arrays are rejected rather than silently corrupted. Use UTF-8 CSV and confirm spreadsheet programs import text, numbers and IDs correctly.
Common questions
What JSON structure can I convert?
The tool supports a top-level array of flat objects or an array of scalar-value rows with consistent column counts.
How are CSV commas and quotation marks handled?
Values containing commas, quotation marks or new lines are quoted and any quote characters are escaped using doubled quotes.
Are uploaded records shared with PackFormulas?
No. Pasted JSON is converted within your browser without uploading it.
