Sometimes while I open any MS Excel file, it shows a message regarding "update the link". These dialog box will come while the excel file contains any external links in formula. It is very much disturbing for working on this file. To find the all external links, just do the followings:
1. Press Ctrl+F to open "Find" dialog box.
2. Type "/" or ".x" or "[" in the find what text area.
3. search it for whole sheet or workbook.
After found delete or replace the formula using the Replace tab of "Find" dialog box.
Note: The external link can also be found in "Conditional Formatting" dialog box. If you see no result after finding the whole workbook or worksheets then check the conditional formatting dialog box of each sheets by going
"Style" tab - "Conditional Formatting" menu - "Manage Rules" menu.
