CSV to JSON Converter — FAQ
Must the first row be a header?
Yes. The first row supplies the key names. If your data has no header, add one before converting.
Why are my numbers in quotes?
By default every cell stays text. Tick the numbers option to convert cells that look like numbers.
Does it handle commas inside cells?
Yes, as long as the cell is wrapped in double quotes, which is how spreadsheet exports normally write them.
