JSON to CSV Converter Online
A JSON to CSV converter takes a JSON array of records and writes it out as the spreadsheet file your tools already know how to open.
Using the JSON to CSV Converter, Step by Step
- Load the JSON: paste an array of objects into the editor on the left, drag a .json file onto the input area, or click Upload File in the toolbar.
- Pick the output from the sidebar: CSV for the standard spreadsheet, TSV when commas live inside values, YAML for a config file, HTML Table for a web page, Markdown for a wiki, or SQL for INSERT statements.
- Read the right pane: the converted output renders the moment the JSON parses and updates again whenever you edit a value.
- Copy or download: Copy puts the output on your clipboard, Download saves it with the right extension for the format you picked.

Cleanest way to flatten a JSON array into a spreadsheet
Our JSON to CSV Converter scans every object in the array before writing the headers. A record with an extra field never loses a column, and a comma inside an address never breaks a row.
Spreadsheet-Ready Output
Our JSON to CSV Converter writes RFC 4180 output so Excel and Google Sheets open the file in one double click.
Six Outputs, One Paste
Switch to TSV, YAML, HTML, Markdown, or SQL from the sidebar without re-pasting the JSON.
Stays in Your Browser
The conversion runs entirely on your machine so a dataset with customer records never hits a remote server.
