CSV to JSON Studio

Transform spreadsheets into clean JSON with flexible parsing controls and instant previews.

Everything runs locally in your browser — nothing is uploaded.

Source CSV
Paste raw comma-separated values or upload a file to start converting.
Large files may take a moment to process, especially when auto-detecting data types.
Parser settings
Fine-tune how PapaParse interprets your CSV before generating JSON.
JSON preview
Copy or download the converted payload alongside a live data snapshot.

Formatted JSON

Converted JSON will appear here after you process a CSV file.

Quick preview
