JSON to TSV Converter

How it works

How to use the JSON to TSV

1. Paste or open JSON

   Paste your JSON, drop a file onto the editor, or load the sample.

2. Adjust the options

   Nested objects are flattened into dotted columns, and values are separated by tabs so commas never need quoting.

3. Copy or download the TSV

   The output updates as you type. Invalid input is highlighted with the exact line and column.

About JSON and TSV

JSON (JavaScript Object Notation) is the standard format for web APIs and configuration: objects, arrays, strings, numbers, booleans and null.

TSV (tab-separated values) is like CSV but uses tabs, so commas inside values never need quoting. Spreadsheets paste it natively.

How the conversion works

Nested objects are flattened into dotted columns, and values are separated by tabs so commas never need quoting. Conversion happens entirely in your browser, so even sensitive data never leaves your device.
