Secure JSON to CSV Converter (and CSV to JSON)
Need to open a JSON file in Excel? Or convert a Spreadsheet back into JSON for your API? Pixedra’s Two-Way Data Converter handles complex data transformations instantly. Unlike older tools, our converter supports Nested Object Flattening, allowing you to turn complex API responses into clean, readable spreadsheet rows. Best of all, it runs 100% Client-Side. Your sensitive data (customer lists, financial records) never leaves your browser.
How to Convert JSON to CSV (Excel)
- Paste Data: Copy your JSON array or object into the left "Input" box.
- Flatten Data: If your JSON contains nested arrays or objects, toggle the "Flatten Nested Objects" switch. This ensures every data point gets its own column in Excel.
- Convert: Click the blue button.
- Download: Click "Download CSV" to save the file, which can be opened directly in Microsoft Excel, Google Sheets, or Apple Numbers.
Why Professionals Choose Pixedra?
Smart Flattening Logic
Standard converters fail when they encounter hierarchical data (e.g., user.address.city). Our tool intelligently flattens these structures into dot-notation columns (e.g., address.city), ensuring no data is lost during conversion.
Enterprise-Grade Privacy
Most online converters upload your file to a cloud server. We do not. Pixedra processes your data locally using your computer's CPU. This makes it safe for converting sensitive business data, client lists, or financial logs.
Bidirectional Conversion
Switch modes instantly to convert CSV back to JSON. This is perfect for developers who need to turn a client's Excel sheet into a database-ready JSON format.
