FREQUENTLY ASKED QUESTIONS

How do I convert JSON to CSV?
Paste a JSON array of objects and the tool maps each object to a row, using the keys as column headers. It also converts CSV back to JSON.
Does it handle nested JSON?
Nested objects are flattened or stringified into cells. For deeply nested data, flatten it first for the cleanest CSV.
Is my data uploaded?
No. Conversion runs entirely in your browser; your data never leaves your device.
