Excel Online connector slow

I am using the Excel Online connector to edit and view excel sheets with power apps. When inserting data into the excel table it is instantly visible in the excel sheet. But when viewing the sheet again in power apps, it takes 1-2 minutes to get synchronized. I could not figure out why Power Apps -> Excel works fast, but Excel -> Power Apps takes one minute. Does someone have an idea?

There are a few factors at play that might affect the times you are seeing:

  • The Excel connector is slow and it gets slower if large amounts of data are exchanged
  • If you are using standard connectors on a Microsoft 365 - level plan, the service level is lower and therefore slower. Per App or Per Person Power Apps plans get better service levels.
  • Your app may not instantly synchronize with your Excel sheet. Expecting frequent updates can bog down the service with a lot unnecessary API calls.
  • If the internet connection is slow, Power Apps as a web service will also be slow


Some effective solutions are:

  • Use a Power Automate flow to do work outside the app if that fits your functionality
  • Use a different backend than Excel whenever possible. SharePoint Lists are noticeably more responsive.

Hope that helps,
