Frequently Asked Questions
Does the CSV need a header row?
Yes. The first row is treated as column headers and used as JSON object keys.
Are quoted fields supported?
Yes. Fields enclosed in double quotes are parsed correctly, including fields with commas and newlines.
Are all values treated as strings?
Currently, yes. CSV has no type information, so all values are output as strings. You can process them further in your application.
What delimiter is supported?
The tool supports standard comma-separated values (CSV). Tab-separated or semicolon-separated formats are not currently supported.
Can I convert CSV without a header row?
The first row is always treated as the header. If your CSV has no header, add column names as the first row before converting.
