How JSON to CSV conversion works

JSON (JavaScript Object Notation) under IETF RFC 8259 represents data in hierarchical tree structures. CSV (Comma-Separated Values) under IETF RFC 4180 represents data in flat 2D grids.

EasyExtract flattens nested JSON paths (e.g. user.address.city) into flat CSV header columns in your browser memory without uploading any data.

How to convert JSON to a CSV table

Paste JSON or drop .json file. Paste your JSON array into the text box above, or drop a .json file onto the drop zone.
Click Convert JSON to CSV. The browser parses the JSON structure and recursively flattens nested objects into column headers.
Review generated CSV. Check the output preview containing RFC 4180 escaped CSV rows.
Download or copy CSV. Click 'Download CSV File' to save your file or 'Copy CSV Text' to paste directly into Excel.

What data gets converted?

Nested JSON Objects: Flattened into dot-notation headers (parent.child).
JSON Arrays: Joined into clean string cells.
Escaped Strings: Handles quotes, commas, and newlines per RFC 4180.

Supported input formats

Supports JSON arrays ([{...}]), single objects ({...}), and JSON text files.

Privacy and security

JSON parsing runs 100% inside your browser memory. Zero JSON data is sent to any server.

Known limitations

Deeply nested JSON trees (over 20 levels deep) may generate wide CSV header structures.

Common use cases

API Analysis — Converting REST API JSON payloads into Excel spreadsheets.
Database Migration — Converting MongoDB or NoSQL JSON dumps to CSV.
Reporting — Generating business reports from JSON analytics exports.

JSON Table Extractor vs JSON Field Extractor

While the JSON field extractor extracts specific key paths, this tool converts full JSON arrays into CSV tables. For XML, use our XML field extractor.
