Convert JSON data to CSV, TSV, or semicolon-separated format. Upload or paste your JSON and get tabular output instantly. All processing happens in your browser.
JSON (JavaScript Object Notation) is the standard data format for web APIs and modern applications. CSV (Comma-Separated Values) is one of the most widely supported tabular data formats, used by spreadsheets, databases, and data tools. Converting JSON to CSV is a common task for developers, data analysts, and anyone who needs to transform API data into a spreadsheet-friendly format.
Our JSON to CSV converter processes your data entirely in the browser — nothing is uploaded to any server. It supports multiple separators (comma, tab, semicolon), flattening nested objects into dot-notation columns, and downloading the result as a CSV or TSV file.
