While upgrading to Excel 2007, you imported calculations from older Excel documents. However, the import wasn’t 100 percent successful and you get the error message #NAME?’ in some cells.
The problem occurs if you have used analysis functions such as ‘CONVERT’, ‘CALENDAR WEEK’ or ‘MROUND’ in the calculation, which you had to activate earlier as using a plug-in. These functions continue to be supported and are now available even directly. But Excel first looks for the plug-in and therefore displays an error message when it can’t find it.With a simple trick, Excel 2007 replaces the incorrect formula in spreadsheet calculations.
Correcting many cells with the same error is really cumbersome. However, you can make Excel reinsert all functions with a simple trick. To do this, select the ‘Home’ tab in the Ribbon bar, then right click ‘Find and Select’ and select ‘Replace’. One character that appears in all functions is the ‘equal to’ sign. Since you do not wish to change anything else, replace it with itself. Thus enter ‘=‘ in both the combination fields respectively and then click ‘Replace all’. That way, Excel replaces all function definitions in the table and now displays correct results.
If only one cell needs to be corrected, select it for editing with the [ key, make your changes, and then press [ With that, Excel looks for the function again and displays the correct result.
