About JSON to CSV
An array of objects is a useful input when each object represents one row. Nested object keys become dotted column paths, while array values are stored as JSON text inside their cells.
Common questions
How are nested JSON objects converted to CSV?
Nested object keys become dotted column paths. Arrays are kept as JSON text in cells rather than automatically expanding into extra rows. Review the flattened table before import.
Should JSON contain an array of objects?
That is usually the clearest table structure: each object becomes a row and its keys supply columns. A single object is also accepted, but unrelated or irregular data may not form a useful table.
Does JSON to CSV upload my selected file?
No. The selected file is processed in your browser rather than uploaded to a conversion server. The page may download processing software or models, and ordinary website connection requests still occur.
Why can the first use take longer?
The browser may first download a processing engine. Speed depends on your browser, available memory and the file's complexity. Keep this tab open until the result is ready.
