Learn how to use Appizy to convert your spreadsheets into secure, reusable online calculators.
What is Appizy?
Appizy is a simple yet powerful platform designed to transform your spreadsheet files into reusable, easy-to-share, and secure online calculators.
With Appizy, everything happens online—there’s no need to install any software on your computer or create an account. Simply upload your spreadsheet, and after conversion, you’ll get an embed link for your web-based calculator. Just copy and paste this code snippet into the website of your choice, and you’re all set!
Conversion principles
In the table bellow are summarized the rules used by Appizy while converting a spreadsheet into a web-application.
| Before | After |
|---|---|
| Cell containing a formula | Output field: non-editable field containing the formula result. |
| Formula dependencies | Regular input field. Calculation are performed each time a value is modified. |
| Other cells | Normal static table cell, reproducing the content. |
General concerns
Top-to-Bottom Display: Consider the application as it will appear in a web browser. Users prefer to scroll vertically, so organize your calculator elements accordingly for a seamless experience.
Avoid Background Color: Instead of using background colors, highlight cells with borders. This allows the background of your tabs to remain clean, while the background of the website where the calculator is embedded will apply naturally.
Hide the Data: If you have a large dataset, move the data to a separate tab and hide it. This prevents Appizy from rendering it as a visual element, which can significantly reduce the size of your web application by a factor of 10 and dramatically speed up calculations.
