Appizy and SpreadsheetWeb start from the same idea: don’t rebuild your Excel logic in a new tool, publish the file you already have. That’s where the similarity mostly ends — the two products are aimed at different buyers.

Where SpreadsheetWeb is strong
SpreadsheetWeb leans into formula coverage — it advertises support for over 500 Excel functions, including newer ones like XLOOKUP, and automatically detects inputs and outputs from named ranges. For finance, engineering, and ops teams publishing internal calculators with heavy formula logic, that depth is a genuine advantage. It also markets lead-capture gating (requiring an email before showing results) as a first-class feature, which is convenient if that’s specifically what you need out of the box.
Where Appizy is strong
- Broader file support. Appizy accepts both .xlsx and .ods files natively. If your source spreadsheet lives in LibreOffice or OpenOffice Calc rather than Excel, you don’t need to convert it first.
- Faster time to a published app. Appizy is built around a three-step flow — upload, customize the design, publish — aimed at getting a professional-looking app live in minutes rather than configuring a business process.
- Design and branding come standard. Themes, custom colors, logo, and layout options are part of the core product rather than an enterprise add-on.
- A usable free plan. You can publish and share calculators without a paid plan first, which matters if you want to validate the tool before committing budget.
Choose SpreadsheetWeb if…
- You’re publishing an internal business tool with deep, complex formula chains and want maximum function coverage.
- Lead-gen email gating is a requirement from day one, not something you’ll add later.
- Your organization already has an established SpreadsheetWeb deployment for other tools.
Choose Appizy if…
- You want your calculator or app live and looking polished today, not after a configuration phase.
- Your source file is a LibreOffice/ODS spreadsheet, or you switch between Excel and LibreOffice.
- You want to try the full product on a free plan before paying anything.
