Macro vs VBA

A macro is a saved sequence of actions—or VBA code—that runs on demand. Record Macro captures clicks; VBA modules scale to loops, conditions, and multi-file jobs.

Weekly report formatting, bulk rename sheets, merge folders of CSV, email exports—anything you repeat. One-off cleaning may be faster with ComTools online merge/dedup.

FAQ

QAre Excel macros safe?

Only enable macros from trusted workbooks. Microsoft blocks unsigned macros by default—see /how-to-enable-macros-in-excel.

QMacro vs formula?

Formulas recalc in cells (use /excel-formula-ai). Macros run procedural steps—copy, export, loop rows.
