Source = Excel.Workbook(File.Contents( Path&Name), null, true), Add the red bits of text into your code.You will now see the code that has been created for your import.Power Query will create the import code (in a custom language called M) behind the scenes, but we will need to edit it slightly. Check the data preview to make sure you have the correct data. Select the sheet that contains your data.Navigate to your folder and select any file.Ī preview of your data will appear in the Navigator window.You can choose any of the files in this step as we are creating an import query that will work for all the files and all the files are structurally the same.
