Frequently Asked Questions
How does CSV to JSON conversion work?
The parser reads the first row as property keys, then converts each subsequent row into a JSON object, forming an array of structured objects.
Does it automatically parse numeric and boolean types?
Yes. Type auto-detection parses numeric strings (e.g. "42", "3.14") into JSON numbers and "true"/"false" into boolean literals.
Can I convert tab-delimited (TSV) or semicolon-delimited files?
Yes. Select delimiter options: comma (,), tab (\t), semicolon (;), or pipe (|).
