Convert CSV files to Excel in Power Automate Flow

In this article, we’ll show how to convert CSV files to Excel XLSX in Power Automate Flow (Microsoft Flow) using Csv to Excel action from Plumsail Documents connector.

Let’s say we have a folder with CSV files and want to convert newly added CSV files to XLSX and store them in another folder.

Our source CSV files have to be stored somewhere. Power Automate (Microsoft Flow) has a lot of connectors for different systems.

Here are just a few of them:

  • SharePoint

  • Salesforce

  • Box

  • OneDrive

  • Google Drive

  • Dropbox

  • SFTP

  • File System

You can store your files anywhere. In this example, we will store our source CSV files and the resulting Excel files in SharePoint folders, but you can get data from any other sources.
