Drop your .json file here or use the manual text box below.
The JSON to CSV converter turns JSON arrays, API-style responses, or pasted objects into a spreadsheet-ready CSV. Upload a .json file or paste JSON directly: arrays of objects become columns (first-seen key order), arrays of arrays use the first row as headers, and single objects become one row. Nested values are stringified into their cell and nulls become empty cells.
Useful for developers and analysts converting API responses or config dumps into CSV for Excel-style review, cleaning, profiling, or charting in Datio.
[{"name":"Alice","tags":["a","b"],"score":98}]

"Alice","[""a"",""b""]",98After converting, the result is a normal table — inspect it, clean it, or profile it like any CSV. CSV to JSON, CSV Viewer, Data Profiler.
It flattens structured JSON into spreadsheet rows and columns. Datio accepts an array of objects, an array of arrays, or a single object — uploaded as a file or pasted as text — and produces an RFC-compliant CSV entirely in your browser.
Paste the JSON into Datio's JSON to CSV tool (or upload the .json file) and choose Convert. Review the table preview with its row and column counts, then copy the CSV text or download the .csv file. Invalid JSON reports the exact parse error.
Nested objects and arrays are stringified into their CSV cell (for example {"a":1} stays readable as text), and null values become empty cells. Column order for arrays of objects follows first-seen key order across all rows.
Use CSV to JSON when spreadsheet data must feed an API, config, or JavaScript app. Use JSON to CSV when an API response or JSON dump must be reviewed, cleaned, or charted like a spreadsheet. Both directions are free in Datio and convert back predictably. CSV to JSON →
Only JSON shapes Datio understands can convert: array of objects, array of arrays, or a single key-value object. Oversized payloads over the browser limit must be split first.
