APIs and apps speak JSON, but spreadsheets speak CSV. This converter bridges the two in your browser: paste a JSON array of objects and it produces a comma-separated table with a header row built from the object keys, ready to download and open in Excel, Google Sheets or any data tool.
How the Conversion Handles Real Data
Each object in the array becomes a row, and the columns are the union of keys found across the objects, so records with an occasional extra field do not break the table — missing values are simply left blank. Values that contain commas, quotes or line breaks are wrapped and escaped following CSV rules, so names, addresses and descriptions survive the trip intact. Nested objects and arrays inside a value are written as compact JSON text in that cell, which keeps the output honest instead of silently dropping data.
How to Convert JSON to CSV
- Paste your JSON into the input box — an array of objects works best.
- Click convert and check the preview table.
- Confirm the header row lists the columns you expect.
- Download the .csv file.
- Open it in your spreadsheet program and start working.

Frequently Asked Questions
What JSON shape does it expect?
An array of flat objects is ideal, like a list of products or users. A single object is treated as a one-row table.
What happens to nested objects?
They are written into their cell as JSON text rather than being dropped, so no information is lost in the conversion.
Is my data uploaded?
No. Parsing and conversion run locally in your browser; your JSON never leaves your device.
