Are comments preserved during conversion?
Comment handling depends on the source and target formats. Formats that support comments (like YAML and TOML) will have them parsed, but since most data interchange formats like JSON do not support comments, they may be stripped during conversion.

The tool validates your input before conversion and displays clear error messages if the data is malformed. This helps you identify and fix syntax issues before attempting the conversion.
Can I convert between nested formats?
Yes, deeply nested and complex data structures are fully supported. The converter preserves the hierarchy, arrays, and key-value pairs from your source format and maps them accurately into the target format.
Is TSV to CSV Converter free to use?
