How does the converter handle nested JSON objects?

Nested objects are flattened using dot notation. For example, {"user": {"name": "John"}} becomes a column header "user.name" with value "John". This preserves the data hierarchy while making it compatible with flat table format.

What happens with arrays inside JSON?

Arrays of objects are expanded into multiple rows, with each object becoming a separate row. Arrays of primitive values are joined with a separator or placed in a single column, depending on the configuration.

Can I use a different delimiter than comma?

Yes, you can choose between comma, semicolon, and tab as the delimiter. This is useful for regions where semicolons are the standard CSV delimiter or when creating tab-separated files for specific applications.

Will the CSV work with Excel?

Yes, the output uses proper CSV formatting with correct quoting and escaping. Values containing commas, quotes, or newlines are properly quoted. The file can be opened directly in Excel, Google Sheets, or any spreadsheet application.

Is there a limit on the JSON size?

Since processing happens in your browser, the practical limit depends on your device's memory. Most JSON files up to several megabytes are handled without issues. For very large files, consider splitting the data first.
