How it works
How it works
- Splits text into lines and cells on commas to form a 2D array.
- If “First row is header” is checked, keys come from row 1 and subsequent rows map by index to objects.
- Values are strings; no automatic type conversion is attempted.
- CSV is deceptively tricky (quotes, commas in quotes, newlines in fields). This tool intentionally handles only simple cases.
