Instantly convert JSON arrays and objects into flat CSV spreadsheets. Secure, strict, and offline.
What we do
Easily convert API responses and JSON object arrays into standard, flat CSV spreadsheets that can be instantly imported into Microsoft Excel or Google Sheets.
When converting JSON to CSV, our engine automatically scans the keys of your objects and constructs a perfectly aligned header row for your spreadsheet.
If your JSON strings contain commas, quotation marks, or physical line breaks, our un-parser automatically wraps them in safe CSV quotes to prevent corrupted columns.
Our tool runs a strict syntax check before converting. If you are missing a bracket or have an invalid comma in your JSON, we instantly catch the error and alert you.
We integrated the premium CodeMirror engine to provide real-time syntax coloring, allowing you to easily read and navigate your data payloads.
Your client lists, financial data, and user databases are completely safe. This tool runs entirely Client-Side inside your browser and never uploads data.
