PRIVACY

Processed content is not uploaded to WorkToolset. Required libraries may be loaded by the site, but the file stays in the browser.

GOOD TO KNOW

Duplicate CSV headers or rows wider than the header must be fixed before JSON conversion.
Nested JSON objects or arrays are serialized inside a CSV cell; they are not flattened automatically.
