Frequently Asked Questions

What JSON formats are supported?

The converter supports JSON arrays of objects, single objects, and objects with data/results/items arrays. Each object becomes a row in the CSV output.

How does it handle nested objects?

By default, nested objects are converted to JSON strings in the CSV. Enable the "Flatten nested objects" option to expand nested properties into separate columns using dot notation (e.g., address.city).

What delimiters are available?

You can choose comma (,), semicolon (;), tab, or pipe (|) as the delimiter. Semicolons are useful for regions that use commas as decimal separators.

Is there a file size limit?

Since processing happens in your browser, limits depend on your device memory. Most devices handle files up to 50-100MB. Very large files may be slower to process.

Does it preserve data types?

CSV is a text format so all values become strings. Numbers, booleans, and null values are converted to their string representations.
