FAQ
Does this handle CSV fields with commas wrapped in double quotes?
Yes โ a field like "Tokyo, Shibuya" wrapped in double quotes is correctly treated as a single value, not split on the comma inside it.
For JSON โ CSV, what happens if objects have different keys?
The header row is built from the union of all keys across every object, and any object missing a given key gets an empty cell for it.
What should I do if the conversion fails?
For JSON โ CSV, the input needs to be a valid JSON array of objects โ check for syntax errors in your input.
