Common questions

Converters FAQ

What can I convert with ToolPool?

The converter collection currently includes CSV and JSON data conversion plus common length, weight, temperature, area, volume, and speed unit conversions.

Are files and values uploaded during conversion?

The converters are designed to process files and values locally in your browser, so the source data does not need to be uploaded to perform the conversion.

Should I verify converted data?

Yes. Review important output before importing it elsewhere, especially when source files contain unusual delimiters, nested data, or values that require precise rounding.
