Merge Multiple JSON Files into One CSV

Combine compatible JSON exports into one spreadsheet-ready CSV without uploading the source files.

A specific workflow: Merge Multiple JSON Files into One CSV

Several API responses use the same record shape and need one CSV for a spreadsheet or database import.

Example input

users-a.json: [{ "name": "Ari", "role": "admin" }]

users-b.json: [{ "name": "Bima", "role": "editor" }]

Expected output

name,role
Ari,admin
Bima,editor

How to use JSON to CSV

  1. Paste or upload your JSON

    Drop one or more .json files into the editor, or paste an array of objects straight from an API response. Nothing is transmitted anywhere.

  2. Parsefy flattens the structure

    Nested objects become dot-notation columns such as user.address.city. Choose Multiple output and repeated arrays are split into their own related tables instead.

  3. Copy or download the CSV

    Take the result as a single CSV file, or as a ZIP of related tables when you split arrays — ready for Excel, Google Sheets or a database import.
