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. Searches for "what is a macro in excel" usually need this definition first, then a safe way to generate code.

How to record a macro

Developer → Record Macro → name it → perform the clicks → Stop Recording. Save as .xlsm. For logic beyond clicks (loops, if/else), paste code from /excel-vba-ai into a module (Alt+F11).

When macros help

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 (/excel-merge, /excel-remove-duplicates).

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.

QDo I need VBA to start?

No. Record Macro covers simple repeats. Use /vba-for-beginners and /excel-vba-ai when you need loops or file batches.
