Frequently Asked Questions

What JSON structure is expected? +
A top-level array of objects with flat keys, like [{"name":"Alice","age":30},{"name":"Bob","age":25}]. Nested structures are flattened with dot notation where possible.
How are commas and quotes in values handled? +
Fields containing commas, quotes, or newlines are automatically wrapped in double quotes and internal quotes are escaped — producing RFC 4180 compliant CSV that opens cleanly in Excel.
What character encoding is used? +
UTF-8 with a BOM, so Excel correctly displays accented characters and non-Latin scripts on first open.
Does the tool touch any server? +
No. Conversion happens entirely in your browser using pure JavaScript — your data stays private.
What delimiter is used? +
A comma, since that is the de-facto standard. If you need semicolon-separated values for European Excel locales, use Find & Replace to swap commas after download.
