Frequently Asked Questions

Can the converter produce an array of objects?

Yes. That format is useful when each CSV row represents one record with named fields.

What happens to numeric and boolean values?

The current tool supports automatic numeric and boolean type conversion, with parsing controls available.

Should I use CSV to JSON for very complex nested data?

It works best when the source is genuinely tabular. Highly irregular structures may need a more deliberate transformation.

Can I choose the output format (array of objects vs array of arrays)?

Yes, you can toggle between an array of key-value objects and a 2D array matrix.
