JSON to CSV Converter
Convert a JSON array into a downloadable CSV spreadsheet.
Upload or paste a JSON file containing an array of objects and download a clean CSV ready for Excel or Google Sheets.
JSON is the standard for APIs and web data exchange, but spreadsheet tools and data analysts need CSV. This converter handles arrays of objects and builds a properly-quoted CSV with headers on the first row, ready to open without any formatting work.
Column order follows the key order of the first object in your array. All rows are included; missing keys in later objects produce empty cells in that column. Nested objects are JSON-serialized into the cell value — flatten your data first for cleaner spreadsheet output.
All processing runs locally in your browser. Your data is never sent to our servers, making this safe for confidential datasets, customer records, and any data subject to privacy regulations.
How to use JSON to CSV Converter
- Step 1: Upload your JSON file or paste JSON directly into the text area. The data must be an array of objects where each object is a row.
- Step 2: Click "Convert" — column headers are automatically detected from the keys of the first object in the array.
- Step 3: Download your CSV file or copy the output. The file opens correctly in Excel, Google Sheets, and most BI tools.
