About JSON to CSV
CSV is the most universal tabular format for Excel, database import, and data analysis. This tool converts a JSON array to CSV locally in your browser, automatically extracting column names from objects, flattening nested fields, and quoting/escaping values that contain commas or newlines. Nothing is uploaded — safe for business data with personal info. Tip: Bookmark this tool for quick access whenever you need format conversion. All processing happens locally in your browser — no data upload, so feel free to paste sensitive content.

FAQ
Must JSON be an array?
Yes. CSV is a 2D table, so JSON should be an array of objects (one object per row). A single object is treated as a one-row table.
How are nested objects handled?
Nested fields are flattened into dotted column names (e.g. user.name) or serialized as a JSON string in the cell.
Will commas in values break it?
No. Values with commas, newlines, or quotes are automatically wrapped in double quotes and escaped per RFC 4180.
What if objects have different fields?
The tool collects every key seen across all objects as the header; cells missing in a given object are left blank.
Can I choose the delimiter?
Comma by default. For TSV (tab) or semicolons, replace in an editor afterward or use the List Converter tool.
Any browser compatibility requirements?
This tool works in all modern browsers (Chrome, Firefox, Edge, Safari). No plugins or extensions required.
Can I use it offline?
After initial load, most features work offline. The core logic runs entirely in your browser with no network dependency.
