How It Works & Capabilities
Convert CSV or TSV spreadsheets into structured JSON arrays. Supports automatic header detection, delimiter detection, and type inference for numbers and booleans.
Step 1
Load json Data
Select your input file or paste source text into the editor.
Step 2

Client-side decoders parse the AST structure and serialize it into valid csv.
Step 3
Export or Copy
Download the output file or copy the converted output straight to clipboard.
Key Features
- ✓ Automatic delimiter detection
- ✓ Automatic header detection
- ✓ Smart type inference (numbers, booleans, null)
- ✓ Array of objects or array of arrays mode
Technical Considerations & Limits
- • Zero-transmission privacy: data processing runs strictly client-side inside your browser environment. Source code, secrets, and payloads are never dispatched to external servers or telemetry systems.
- • Processing speed depends entirely on your device hardware (CPU & available RAM). Extremely large files (>200MB) may exceed browser memory limits.
