JSON to CSV

About the JSON to CSV Converter

The JSON to CSV Converter transforms structured JSON arrays into spreadsheet-friendly Comma-Separated Value tables. Data analysts, business teams, and developers use this constantly to move API responses, database exports, and webhook payloads from a programmer-friendly format into Excel, Google Sheets, or BI tools that work best with tabular data.

How the conversion works

The converter scans your JSON array, collects every unique key across all objects to form the CSV header row, then writes one row per object with values aligned to columns. Missing values become empty cells, nested objects are optionally flattened into dot-notation columns (user.email), and arrays inside objects can be joined or serialised as JSON depending on your preference.

How to use it

1. Paste your JSON array into the input area — an API response, an export from a NoSQL database, anything.
2. Click Convert.
3. Copy the CSV output or download it as a .csv file ready for Excel.

Common use cases

Exporting customer data from a JSON API into Excel for filtering, migrating MongoDB collections to Google Sheets for non-technical teammates, converting webhook payloads into a daily CSV digest, preparing analytics data for visualisation in Tableau, sharing API responses with stakeholders who don’t read JSON, and quickly inspecting large JSON arrays in a spreadsheet view.

Privacy and edge cases

Conversion happens entirely in your browser using a native JSON parser. Your data is never sent to our servers. Special characters (commas, quotes, newlines) in values are automatically escaped per RFC 4180 so the CSV opens correctly in Excel, Numbers, and Google Sheets without manual cleanup.
