Excel Tab Name Changes

Hi,

Not sure how to do a folder...i have this right now: The Orange Bold writing is the sheet name that will constantly change. This time it is 32, next week will be 33. it is the only sheet in the file. 

let
Source = SharePoint.Files("https://jnj.sharepoint.com/teams/OneStopShop", [ApiVersion = 15]),
#"J&J Kroger OvS xlsx_https://jnj sharepoint com/teams/OneStopShop/Shared Documents/Kroger/" = Source{[Name="J&J Kroger OvS.xlsx",#"Folder Path"="https://jnj.sharepoint.com/teams/OneStopShop/Shared Documents/Kroger/"]}[Content],
#"Imported Excel Workbook" = Excel.Workbook(#"J&J Kroger OvS xlsx_https://jnj sharepoint com/teams/OneStopShop/Shared Documents/Kroger/"),
#"UPC Matrix (32)_Sheet" = #"Imported Excel Workbook"{[Item="UPC Matrix (32)",Kind="Sheet"]}[Data],
#"Removed Top Rows" = Table.Skip(#"UPC Matrix (32)_Sheet",2),
#"Promoted Headers" = Table.PromoteHeaders(#"Removed Top Rows", [PromoteAllScalars=true])
