Optimization Breakdown
This code copies all your data in one go instead of transferring cell by cell. It instantly moves a large range between sheets and keeps your screen from flickering. No more long waits for big copy operations!

Optimization Breakdown
Instead of updating each cell in Excel one at a time (which is slow), this macro loads all the values into memory, makes the changes fast, then writes the entire block back at once. This is much quicker for big changes!

Optimization Breakdown
This optimized loop switches off Excel features that slow your macro, then uses arrays for processing—all making it run far faster! Good for repetitive actions or longer loops, especially with larger worksheets.

Optimization Breakdown
This clean-up macro helps reduce file size by trimming unused data and removing objects you don’t use. Your workbook loads faster and feels snappier after running it!

Pro Tip

Mention the part of your macro that is slow. For best optimizations, describe the action you’re doing, like “copying large ranges” or “looping with IFs”.

3 steps to fast Excel workbook performance.

Turn slow, not responding spreadsheets into production ready workflows with AI VBA optimizer.

1 Insert your existing code

Drop any macro into editor: recorded macros, inherited workbooks, or your own creations. The ai code optimizer immediately analyzes structure, identifies performance bottlenecks, and maps array-based opportunities.

2 Describe the desired outcome

Write plain language prompts: “Make this run 5x faster,” “Add inline comments,” “Fix memory leaks,” or “Convert to late binding.” The ai to optimize code understands excel vba ai context without technical jargon.

add a optimization prompt for AI to improve the code

3Review changes and iterate

Check the AI edits of every modification. Accept changes that AI made, reject, or prompt further refinements. This iterative workflow ensures you maintain full control while the ai optimize code process continues.

Frequently Asked Questions

Do I need to know how to code to optimize vba?

No. If you can describe what you want in plain English, the ai to optimize code handles everything else. It’s built for Excel users, not developers.

How is Ajelix vba code optimizer different from just using ChatGPT?

Ajelix knows Excel inside and out, not just general programming. With Ajelix you get a real editor with version control and side-by-side comparisons, not just a chat window.

What if the AI breaks my macro?

Every change shows up in a clear before/after view. You can reject any modification with one click, and one-button rollback restores your original code instantly. Plus, the AI explains why it made each suggestion.

Can this handle huge, complex macros?

Yes. Enterprise clients can use it on multi-module projects with thousands of lines. The ai code optimizer maps how different parts connect and suggests improvements to the overall structure.
