Чего ожидать
- CSV values default to strings - a number like
9.99stays quoted unless the tool applies type inference (pandasdoes; online tools vary). - A header row is required; without one, keys default to column indexes like
0,1,2. - A delimiter mismatch - commas expected but file uses semicolons - collapses each row into a single JSON field; always specify the correct delimiter.
Часто задаваемые вопросы
Do I need to install anything to convert CSV to JSON?
No - our free converter above works without installation. For large or sensitive files, use Python with
pandas locally.Why are all my JSON values strings instead of numbers?
CSV has no type information, so converters output strings by default;
pandas infers numbers automatically, but most online tools do not.My CSV uses semicolons instead of commas - will it still convert?
Yes, but specify the delimiter: in
pandas add sep=';' to read_csv, and in csvjson use csvjson -d ';' file.csv.Can I convert JSON back to CSV?
Yes - though the round-trip is lossy: nested JSON objects need flattening first, and typed values become plain strings in CSV.
