About data converters
These free data converters move information between the formats that spreadsheets, databases and APIs expect. Common jobs include JSON to CSV, CSV to JSON, CSV to Excel, Excel to CSV and XML to JSON, plus YAML, TOML and SQL conversions. Beyond conversion, the CSV viewer, CSV validator, Split CSV and CSV remove duplicates tools help you inspect and clean files, and checkers such as the JSON flattener and Missing data profiler explain what a dataset contains.
Before converting a large file, open it in the CSV viewer or a validator to confirm the delimiter, header row and encoding. Fixing those first prevents shifted columns and broken characters in the output.

Common questions
Is my data uploaded when I convert a file?
The main converters, including JSON to CSV, CSV to JSON, CSV to Excel, Excel to CSV and XML to JSON, run in your browser. Your file is read and converted on your device and is not sent to our server during the conversion.
How are nested JSON objects handled in CSV?
CSV is a flat table, so nested objects are flattened into column names that show their path. Arrays may be joined or expanded depending on the options. If you need control over the result, run the JSON flattener first and review the columns.
Why do special characters look wrong after conversion?
This usually means the source file uses a different text encoding than expected. Save the original as UTF-8 where possible, then convert again. For Excel, the CSV to Excel tool avoids the encoding guesswork that happens when you open a raw CSV.
