Convert JSON to CSV Online

Turn a JSON array of objects into a clean CSV, right in your browser. Paste your JSON and download a spreadsheet-ready file.

Your file never leaves your device.

How to convert JSON to CSV

Each object in your JSON array becomes a row and the object keys become the column headers, so your data lines up perfectly in a table. The CSV opens directly in Excel, Google Sheets and any data analysis tool.

  1. Step 1: Paste your JSON

    Paste a JSON array of objects into the converter.

  2. Step 2: Convert locally

    Your JSON is converted to CSV right in the browser. Nothing is uploaded.

  3. Step 3: Download the CSV

    Download the .csv file and open it in your spreadsheet.

Good to know

  • An array of objects works best. A single object is treated as one row, and nested objects are flattened with dot notation for tabular outputs.
  • Invalid input is reported with a clear error instead of producing a broken file.

Why use this JSON to CSV converter?

  • Perfect structure: each object becomes a row and the keys become clean column headers.

Is it free?

JSON to CSV runs entirely in your browser. Your data is never uploaded to a server and never leaves your device.

About the formats

What is JSON?

JSON (JavaScript Object Notation) is a lightweight format for storing and exchanging data as collections of key-value pairs. It grew out of JavaScript but is now supported by nearly every programming language. JSON is the de facto standard for APIs, configuration files and structured data.

Use JSON when machines exchange data, REST APIs, web apps, configuration and tool settings. Its predictable structure makes it easy to parse, so it is the natural choice whenever data needs to be read by software.

What is CSV?

CSV (comma-separated values) is a plain-text format that stores tabular data, one row per line and fields separated by commas. It needs no special software: any text editor, spreadsheet application or database can read it. Because of its simplicity, CSV is the universal interchange format between databases, spreadsheets and other programs.

Use CSV whenever you need to move tabular data between systems, exporting a database, importing contacts or sharing a table with someone who uses different software. Choose CSV when plain, predictable data matters more than formatting.
