Best approach to upload ~50,000 Excel rows to SharePoint (weekly refresh scenario)

(1) ShareShare
ReportReport
Posted on by 3,291

Hi everyone,

I’m looking for guidance on the most reliable and efficient way to handle a recurring data upload process using Power Platform tools.

Scenario:

  • I have an Excel file containing approximately 50,000 rows.

  • The data needs to be uploaded into a SharePoint list.

  • This process must run on a weekly basis.

  • Before uploading, I need to completely delete all existing records in the SharePoint list and then insert the new dataset.

  •  

Current challenges:


  • Performance concerns when handling large volumes (50k rows).

  • SharePoint delegation limits and throttling.

  • Efficiently deleting and reloading the data without errors or timeouts.

  • Maintaining reliability for a scheduled (automated) process.


  •  

Questions:

  1. What is the best architecture or approach to handle this volume (Power Apps, Power Automate, Dataflows, Azure, etc.)?

  2. Is using Power Automate with batching or pagination sufficient, or should I consider something like SharePoint REST API, Azure Functions, or Dataflows?

  3. What’s the most efficient way to delete all records from a SharePoint list at this scale?

  4. Are there recommended patterns for bulk insert into SharePoint to avoid throttling?

  5. Would it be better to avoid deleting/reinserting and instead do incremental updates (even though the dataset changes completely each week)?


  6.  
 

Any best practices, sample architectures, or proven approaches would be greatly appreciated.

 

Thanks in advance for your help!
