Custom File Upload and Processing: Set up a custom form on Power Pages for Excel uploads, then use Power Automate or a custom API to parse and insert data into Dataverse, tailored to your needs.
Dataverse Excel Import Feature: Direct users to utilize Dataverse's built-in Excel import functionality, allowing them to upload pre-filled templates directly into the Dataverse table.
Use Power Apps Component Framework (PCF): Develop a PCF control for the portal, enabling users to drag and drop Excel files, which are then processed and imported into Dataverse for bulk data handling.
