I'm trying to create a formula that will look up the same cell only across multiple workbooks. Someone has created a new workbook each week and entered one point of data I want to collect over time in the same cell of each workbook. Each work book has the same name but ends with a different date. Example: "WorkbookABC 1-1-2018.xlsx", then "WorkbookABC 1-8-2018.xlsx",.... etc. I'm guessing I need to use the indirect function. Any ideas on how to create a formula i can just drag down over time which will lookup into the new workbook as well as look back into old workbooks based on the date I want?
