Convert JSON arrays and objects to CSV format instantly. Free online JSON to CSV converter with custom delimiters, header control, and Excel-friendly output.
The Tooloogle JSON to CSV Converter turns JSON arrays and nested objects into spreadsheet-ready CSV files. Whether you're exporting API responses for analysis, preparing reports for non-technical colleagues, or migrating data into Excel or Google Sheets, the converter produces clean, properly escaped CSV in one click.
Array of objects — the most common JSON shape becomes one row per object, with keys as headers.
Nested object flattening — nested keys become dotted column names (address.city).
Custom delimiter — comma, semicolon, tab, or pipe (semicolon is needed for European Excel locales).
Header control — include or omit the header row; reorder columns; rename keys.
Quote handling — values containing commas, quotes, or newlines are automatically quoted and escaped.
Excel-friendly output — UTF-8 with BOM option so accented characters render correctly in Excel.
Preview & download — preview the CSV inline, then download as .csv.
Paste JSON or drop a .json file.
Pick the delimiter and header options (defaults work for most cases).
Optionally rename or reorder columns.
Copy the CSV output or download as a file.
Exporting API data for analysis in Excel or Google Sheets. Sharing JSON datasets with non-technical stakeholders. Preparing data for tools that only accept CSV (BI dashboards, mailing platforms). Converting MongoDB / Firestore exports to relational format.
For European Excel users, choose semicolon as the delimiter and enable the UTF-8 BOM — otherwise accented characters and decimals look wrong.
Flatten nested objects only if your downstream tool can't handle dotted keys; otherwise consider exporting JSON Lines instead.
If your JSON contains arrays inside objects, decide whether to join them (e.g. with ;) or skip them — CSV doesn't natively support nested arrays.
Conversion happens locally in your browser. Your JSON data is never uploaded or stored.
