Frequently asked questions
How are CSV headers handled?
The first row is treated as the header, and each column name becomes a key in the resulting JSON objects.
What if my data contains commas or quotes?
Properly quoted CSV fields are parsed correctly, so values containing commas or quotation marks are preserved during conversion.
Can it convert JSON back to CSV?
Yes. A JSON array of objects is flattened into rows and columns, ready to open in a spreadsheet.
