There is also a web version of Excel, which works directly from the browser without installing additional programs on your computer. Is called Excel Online and it's completely free, you just need a Microsoft account to use it.
Although it allows you to protect your documents by setting them to read-only mode, Excel Online does not allow you to set passwords as it does in Excel for Windows or macOS. Likewise, it does not allow you to open password-protected Excel documents via the desktop version of the program.
If these limits aren't a big deal to you, connect to Excel Online, log into your Microsoft account, and choose whether to create one blank workbook (to create a new Excel file) or whether to open an existing document. In the latter case, however, you must first upload the file to OneDrive, the Microsoft cloud storage service (which I told you about in depth in my dedicated tutorial).
Once you have opened the document you want to set in read-only mode in Excel Online, click on the button Fillet located at the top left, select the item information from the menu that appears on the side and click on the icon Protect Workbook. The game is done!
