An ex company employee created an excel spreadsheet which draws data from a .txt file and creates a graphical output using macros which is fully compatible with Excel 2003. The spreadsheet does not work with Excel 2007 and newer.
We require someone to look over the spreadsheet and fix the coding to enable the spreadsheet to be compatbile with recent Excel versions.
I can provide the spreadsheet and an example of the data we used to evaluate costings.
