Why Convert JSON to CSV?

JSON is the language of APIs, but spreadsheets speak CSV. Converting JSON to CSV lets you open API responses, exports, and log data directly in Excel, Google Sheets, or any analytics tool. This converter flattens an array of JSON objects into rows and columns, using the union of all keys as the header row.

Common use cases

  • You have a JSON file and need it in CSV format for exporting database records for analysis in excel or google sheets.
  • The target software or platform requires CSV but your file is in JSON.
  • You want to reduce file size or improve compatibility without using desktop software.
Keep in mind: CSV has no standard for data types, number formats, or multiple sheets — all values are stored as text. Commas inside values require careful quoting.

How to Convert JSON to CSV

  1. Upload or drop your JSON file into the converter above.
  2. Adjust any output settings for CSV if needed.
  3. Click Convert and download your converted file instantly.

About the Formats

JSON (JavaScript Object Notation)

JSON is the standard data-interchange format of the web. It represents structured data as nested objects and arrays in plain text — human-readable, language-independent, and natively supported by every programming language and API in common use.

Compatibility: Universal — every programming language, browser, and modern tool reads JSON.

CSV (Comma-Separated Values)

CSV is a plain-text format for tabular data where each line represents a row and commas separate column values. It is the most universal data-exchange format — virtually every database, spreadsheet application, CRM, and analytics tool can import and export CSV files without any special configuration.

Compatibility: Universal — supported by Excel, Google Sheets, LibreOffice, every database system, and virtually all data tools.

100% Private & Browser-Based

Your files never leave your device. All conversion happens locally in your browser — nothing is uploaded to any server. No sign-up required.
