Common questions
Can I change the order of the columns, not just remove some?
Yes — once you have picked which columns to keep, drag them (or use the arrow buttons) into the order you want the output file to use.
Does removing columns affect the row data itself?
No — rows and their values in the columns you keep are unchanged. Only the columns you did not select are left out of the download.
What if two columns have the same header name?
Each is treated as its own column and can be selected independently, though duplicate names in the header row can make it harder to tell them apart — renaming them in the source file first avoids the confusion.
