Hi @barney1234 ,
Try the below flow.
1) Use a when a file is created in a folder trigger and then get metadata

2) Initialize a Boolean variable and set it to @false. Add a Get worksheets action to get all the worksheets in your Excel

3) Loop through each Excel worksheet and add a condition where Name of worksheet is equal to Name of file (from Get File Metadata). If found, set Boolean variable to @true

4) Exit the loop. Add another condition to check whether your Boolean is false (i.e. it did not find a worksheet with the same name). If true, create a worksheet with the name of the file (from Get File Metadata).
