This is really horrible that a basic "manage rules" function is not built in to the web version. I have 50+ people working on six spreadsheets in SharePoint and now I have to edit each cell on my desktop and re-upload the file. It is worsened by the fact that the data online is live, so I have to copy that data into my desktop master file, make the conditional formatting changes, delete the online file and upload a new one to every region who uses the document so it is seamless to them. This is just plain ridiculous and poorly planned by Microsoft.
