# CSV File Directives

_Updated May 2023_

To assert greater control over details of the output file formatting, you may optionally insert //XL directives into the CSV file. These should be at the top, before any data lines, except in the case of the //XL,SetRow directive, which may be inserted anywhere above the affected row(s).

The syntax for the //XL directives is a bit tricky, and differs from normal A-Shell conventions. See [Notes on Syntax](notesonsyntax.md).
