What JSON works best?

A JSON object with plain values — strings, numbers, booleans, and null. That single record becomes one CSV row with a header of its key names.

What about nested objects, arrays, or a big list of records?

Nested objects and arrays inside the record are flattened into readable text, and null is written as null. One JSON object per file is converted at a time; convert each record file separately rather than uploading a giant array.

Will my CSV open correctly in Excel or Google Sheets?

Yes. The output follows standard CSV quoting, so commas, quotes, and line breaks inside values survive the round trip.

What if the file is invalid?

No CSV is produced for a file the converter can't read. Upload a valid JSON record and try again.

Convert JSON data to CSV online

Have a JSON record and need a spreadsheet row? This page turns record-oriented JSON into a CSV report you can open in Excel, Google Sheets, or any table tool.

How to convert

Upload a JSON file up to 2 MB.
Press Convert file.
Download the CSV from the result page.

What you get

A comma-separated report with a header row naming each column, then one line for the record. Values that could confuse a parser — commas, quotes, newlines — are quoted, so the file stays valid.

A file like this:

{
  "name": "Ada Lovelace",
  "born": 1815,
  "field": "mathematics",
  "active": true,
  "note": null
}

produces a CSV like this:

SourceFile,name,born,field,active,note
record.json,"Ada Lovelace",1815,mathematics,true,null

The first column records the source file; the rest are your JSON keys. Plain values are written as-is, nested objects and arrays become readable text, and null is written as null.
