How do I add a hyperlink in one HTML file to another HTML file?

Question

I have a Documents folder, which is of the Document Library type. Inside, I have a temp folder that includes two HTML files: a.html and b.html. In the a.html file, there's a link to the b.html file (B file). When I open the a.html file using an HTML viewer and click on the B file hyperlink, I receive a "404 NOT FOUND" notification. I also tried using the absolute path without success. I know that I can use Pages in the Page library, but this solution doesn't help me enough. I want to use SharePoint as the place where I will add my HTML reports, minimizing the effort required.

Hi @yosa,

SharePoint Online tenants handles the file open experience using the strict model. As a result, all files which can potentially cause harm (e.g. a html file having embedded script) are not executed in the browser but downloaded or shown as raw content (html preview in the modern user experience).

For these html/html files the remediation is simple: if a user/app with site owner or site collection admin permissions renames the html/htm files to ASPX files then these files do open again. Below SharePoint PnP PowerShell shows a how this can be done.

Connect-PnPOnline -Url https://contoso.sharepoint.com/sites/permissive -Verbose
Rename-PnPFile -ServerRelativeUrl /sites/permissive/html/newfile.html -TargetFileName newfile.aspx -OverwriteIfAlreadyExists

After rename then html files, you will need to allow custom script to enable aspx file. Please follow the steps in the document
