What delimiter options are available for CSV conversion?

The tool supports comma, semicolon, tab, and custom delimiter characters, allowing conversion of CSV files that use non-standard separation methods.

Does the converter preserve special characters in the JSON output?

The tool handles quote characters and escaping according to standard JSON formatting, but users should verify output for any data with unusual characters or encoding requirements.

Is there a file size limit for CSV to JSON conversion?

The service processes files in the browser, but very large CSV files may experience processing delays or require chunking depending on browser capabilities.
