As answered by people managing ShellNewHandler and ExcelErrorFinder.
ExcelErrorFinder's answer:
It's the only free, browser-based Excel auditor that not only finds errors but explains why they happened and how to fix them all without uploading your file anywhere.
ExcelErrorFinder's answer:
Competitors are expensive, require installation, and target enterprise teams. ExcelErrorFinder is free, instant, works in any browser, and is safe for confidential files. No setup. No cost. No compromise on privacy.
ExcelErrorFinder's answer:
Finance professionals, accountants, analysts, and small business owners who use Excel daily and need to trust their spreadsheets before they go out.
ExcelErrorFinder's answer:
One statistic: 94% of business spreadsheets have errors. Professional audit tools exist but cost hundreds of dollars and require installation. ExcelErrorFinder was built to give everyone access to the same quality of audit — free, instant, private.
ExcelErrorFinder's answer:
SheetJS for in-browser Excel parsing, vanilla JavaScript for all audit logic, and Claude via OpenRouter for the plain-English AI explanations. Fully serverless — no backend.
ExcelErrorFinder's answer:
The tool is free with no signup, so we don't track users by design. Our audience spans finance, accounting, consulting, and small business — anyone who needs to trust their spreadsheets.

I've always used ShellNewHandler for this. It's a really simple portable utility that allows you to remove most of the items from that menu. Tested it out on Windows 11 and it's still compatible. Source: over 5 years ago
