About JSON to CSV

Convert JSON arrays into RFC 4180 compliant CSV, TSV, or custom-delimited spreadsheet files

RFC 4180 Export100% Client-Side
Data Flow:Input: JSON Array of Records➔Output: CSV / TSV File (.csv)
A JSON to CSV converter transforms structured JSON data into standard Comma-Separated Values (CSV) or Tab-Separated Values (TSV) files for use in Microsoft Excel, Google Sheets, or data analytics software.

The JSON to CSV converter handles flat and nested JSON arrays, properly escaping commas, quotes, and line breaks in compliance with RFC 4180. It allows you to select custom delimiters (comma, tab, semicolon), configure header inclusion, and download ready-to-use CSV files.

RFC 4180 compliant CSV generation with quote and delimiter escaping
Delimiters: Comma (`,`), Tab (`\t`), Semicolon (`;`), Pipe (`|`)
Automatic column header inference from record keys
Instant real-time preview and one-click file download
Important Note: Deeply nested objects and arrays within records are serialized as JSON strings or flattened based on selected options to prevent column distortion.
Strict client-side execution. Your payload is never transmitted across the network or stored in external servers.
