Frequently asked questions
Does it handle commas inside quoted fields, like "Smith, John"?
No — each line is split on plain commas with no awareness of quotes, so a quoted field containing a comma gets split into two columns instead of staying together. It works well for simple, comma-free values, not full CSV-with-quoting.
Are numbers converted to actual numbers in the JSON output?
No — every value comes out as a string, even ones that look numeric, since the parser just splits text on commas without any type inference.
Where do the JSON property names come from?
The first line of your CSV — whatever's there, split on commas, becomes the key names used for every row after it.
