FAQ
- Are rows with missing values safe?
- Yes, missing values are automatically padded with empty spaces to prevent layout misalignment.
- Can I reorder columns in a CSV file that has no header row?
- Yes, you can still use it — but since the tool treats the first line as column names, a file without a real header will get placeholder names like "Column1, Column2" assigned automatically. Just remember the resulting first row is actually a data row, not a header.
