Transform data between JSON and CSV formats instantly. Perfect for migrating data between APIs and Spreadsheets (Excel/Google Sheets).
JSON (JavaScript Object Notation) is the standard for web data APIs, while CSV (Comma Separated Values) is the king of spreadsheets. Converting between them is essential when moving data from a database or API into Excel for analysis, or importing spreadsheet data into a web application.
Download data from a REST API (JSON) and convert it to CSV to open it in Microsoft Excel or Google Sheets for reporting.
Prepare spreadsheet data for database import by converting CSV files to structured JSON documents.
Bridge the gap between Code and Spreadsheets.
Stop manually formatting data. Our converter ensures consistent quoting and escaping, so your data looks exactly right whether it's in a JSON config file or a financial report.
Standard format for any platform.
For JSON to CSV, nested objects are stringified (e.g., `{"a": 1}`) inside the cell to preserve the data structure within a flat CSV format.
No. All conversion logic runs locally in your web browser using JavaScript. Your sensitive data never leaves your device.
