AI Excel VBA Explainer

Explain Excel VBA Code

How it works

Understand Any VBA Macro

Inherited a workbook full of macros? Get a clear explanation before you run anything:

Paste the code

Copy the macro from the VBA editor (Alt+F11) and paste it into the input box — whole procedures or just the part you're unsure about.

AI explains the logic

You get a structured explanation: a short summary of what the macro does overall, plus a line-by-line breakdown of what each line does.

Decide with confidence

Run it, fix it or rewrite it — now that you understand what the code is meant to do.

How it reads code

Understand macros line by line

Paste a macro and get an overall summary plus a table that explains every meaningful line.

Line-by-line table

Each line of code sits next to a plain-language note, so you can follow the macro from top to bottom.

Loops & branches

For, For Each, Do loops and If branches are called out so the control flow is obvious.

Ranges & cells

See what each Range, Cells and Worksheet reference in the code is pointing at.

Subs & events

What the macro declares, what triggers it, and what it leaves behind when it ends.

Summary first

A short plain-English description of what the whole macro achieves sits above the detail.

Inherited workbooks

Ideal for auditing macros in files you inherited before you trust and run them.

Frequently Asked Questions

What does the VBA Explainer do?

It reads VBA code and produces a plain-language explanation of what the macro does — an overall summary plus a line-by-line breakdown.

Why should I check macros before running them?

Macros can modify or delete data, write files and interact with other applications. Understanding the code first — especially in workbooks you received from others — protects your data.

Can it explain long modules?

Yes — paste whole procedures or modules. Very long code is explained section by section; for best results, paste one logical procedure at a time.

Is it free to use?

Yes — free, no sign-up, no ads. Use it right in your browser.
