I have a large spreadsheet containing multiple pivot tables. Something in the spreadsheet (I assume a pivot table) is pointing to a file that doesn't exist anymore. When I click Refresh All to update the pivot tables, I receive an error "Sorry, we couldn't find <path and file name of the deleted file>. Is it possible it was moved, renamed or deleted?" I know this file doesn't exist anymore. But my question is - how do I quickly/easily find what is pointing to this deleted file? I have performed a Find to search on the filename but the filename isn't found. Other than navigating to each pivot table and opening Change Data Source to visually check where it is pointing to, how can I find what is pointing to the deleted file?
