JSON to CSV Online

Updated 2026-08-19

Convert JSON to CSV online for free. Paste a JSON array of objects and SnapTools turns it into clean, spreadsheet-ready CSV — each object becomes a row, each key a column — that you can copy or download and open straight in Excel or Google Sheets. It all runs in your browser; nothing is uploaded.

This is the fastest way to get JSON data in front of people who live in spreadsheets, or to bulk-load records into a tool that expects CSV. Need the reverse? The CSV to JSON converter takes you back.

// how to use

  1. 1 Paste a JSON array of objects into the input panel.
  2. 2 SnapTools turns each object into a row and each key into a column header.
  3. 3 Copy or download the CSV, ready for Excel, Google Sheets, or any spreadsheet.

// faq

What JSON shape does it expect?
An array of objects works best — each object becomes a row and its keys become the column headers. A single object is treated as one row.
How are nested objects handled?
Nested values are flattened or JSON-encoded into the cell so the CSV stays valid. Flatten deeply nested data first if you need each field in its own column.
Will it open in Excel or Google Sheets?
Yes. The output is standard comma-separated CSV that imports directly into Excel, Google Sheets, Numbers, and most data tools.
Is my data uploaded?
No — the conversion runs entirely in your browser, so your data stays on your machine.
Can I go the other way, CSV to JSON?
Yes — use the CSV to JSON tool to convert spreadsheet data back into JSON.
