JSON to CSV Converter

JSON is perfect for machines but awkward in a spreadsheet. This free JSON to CSV converter transforms a JSON array of objects into a clean, delimited CSV table — complete with headers, proper quoting and escaping — exactly what Excel and Google Sheets can open. Paste it, convert it, or download it.

What is a JSON to CSV Converter?

A JSON to CSV converter turns a JSON array of objects into a flat table in CSV (comma-separated values) format. Each object becomes a row, and the property names become the column headers, so a list like [{"name":"Alice","age":30}] becomes a spreadsheet with a name and age column.

It is the bridge between structured data and spreadsheets. JSON is the standard for APIs, exports and databases, but most people analyse data in a table. The converter handles the details for you: it flattens the first row’s keys into headers, adds any extra keys found in later rows, and wraps values in quotes and double ups the internal quotation marks wherever a field contains a comma, quote or newline, so your data survives a round trip.

Anyone moving API output into Excel, exporting analytics to a client, or importing data into Google Sheets will appreciate a tool that produces clean CSV without writing a script. Because the conversion is local, you can pass customer data through it without uploading anything.

How to use the JSON to CSV Converter

Paste a JSON array of objects into the input area.
Click Convert (or Convert JSON).
Read the CSV output, complete with headers, in the result area.
Click Copy to copy it, or Download to save a .csv file you can open in Excel or Google Sheets.
Use Clear to reset and convert another JSON block.

Example

Input: [{"name":"Alice","age":30},{"name":"Bob","age":25}]

Output (headers from the keys):

name,age Alice,30 Bob,25

Both rows become entries under the name and age columns, ready to open in any spreadsheet.

Common use cases

Loading API output into Excel or Google Sheets for analysis.
Turning a JSON export into a tabular report for a client.
Preparing structured data for a CSV import into a CRM or database.
Converting a small database dump into rows you can sort and filter.

Pro tips

Make sure your JSON is an array of objects for the cleanest table; a single object is converted into one header row and one data row.
The converter escapes commas, quotes and newlines automatically, so fields that contain punctuation are not broken.
If you want Excel-friendly formatting, be consistent with your key names — extra keys found in later rows are added as new columns.
Check the row count in the status message to confirm nothing was dropped before you download.

FAQ

What is JSON to CSV conversion?

It is the process of taking JSON data, typically an array of objects, and turning it into a flat table with column headers and comma-separated data rows, ready for a spreadsheet.

Does it handle nested objects or arrays?

This converter works best with flat objects. Nested arrays and objects are stringified into a cell, so complex structures may need flattening first.

How are headers generated?

The property names of the objects in your JSON become the column headers of the CSV.

What about commas or quotes inside a value?

The converter escapes them automatically by quoting the cell and doubling internal quotes, so Excel and other tools read the data correctly.

Can I download the result as a file?

Yes. Click Download to save a .csv file you can open in Excel, Google Sheets or any other spreadsheet app.

Is my JSON uploaded or stored?

No. The conversion runs entirely in your browser, so your data never leaves your device.

Does it accept a single JSON object?

Yes. A single object is treated as a one-row table and converted with its keys as the headers.

Is it free?

Yes, free and unlimited with no signup required.
