Formula Audit XL: the PerfectXL alternative
PerfectXL grew out of spreadsheet-risk research at TU Delft and has become a known name in formal risk and quality analysis, with a Windows add-in and a web-based platform for reporting and comparison. Formula Audit XL sets out to do something narrower: fast, in-Excel auditing with a keyboard shortcut for each check and a one-click health report, priced openly for individuals and small teams.
If you are weighing the two, the question is mostly about shape. PerfectXL is a risk platform you analyse models with; Formula Audit XL is an add-in you audit inside Excel with. The free tier and the browser tools are the quickest way to see which fits how your team actually works.

When PerfectXL is the better choice
- PerfectXL has a longer track record in formal spreadsheet risk work, with roots in academic research, and a risk methodology that audit and compliance teams may already follow.
- Its web-based analysis and reporting suit organisations that want shareable reports and a browser workflow rather than a tool that lives inside Excel.
- The wider suite covers model comparison and collaboration features that sit outside the scope of a focused audit add-in.
Why teams switch to Formula Audit XL
- Pricing is published, so an individual or small team can buy without booking a demo or waiting for a quote.
- The free tier and the browser-based checks let you test the tool on your own models before paying anything.
- Everything happens inside Excel where you already work, with keyboard shortcuts for each check rather than a separate web step.
- For teams whose main need is fast in-Excel auditing rather than a full risk-platform rollout, the focused feature set is quicker to learn.
Frequently asked questions
Is Formula Audit XL a direct PerfectXL replacement?
It covers the core audit overlap: tracing, hardcode and external-link detection, inconsistent-formula and named-range checks, and a whole-workbook health report. PerfectXL also offers web-based reporting and a broader risk-platform workflow, so the fit depends on whether you want an in-Excel add-in or a platform.
Does Formula Audit XL analyse my file in the cloud like the PerfectXL web app?
No. The add-in runs entirely inside Excel on your machine, and the free web tools run in your browser. Your workbook contents are never uploaded.
Does Formula Audit XL work on Mac?
No. It runs in Excel for Windows only (2016, 2019, 2021 and 365). PerfectXL's web app is reachable from any browser, which can be an advantage for Mac users.
Can I try it before buying?
Yes. There is a free tier inside Excel and free browser tools, so you can run real checks on your own models before choosing a paid plan.
