Ever send a spreadsheet to a client or vendor and wonder if it has been changed? Ever have a spreadsheet that multiple people use and you don't know what has changed on it? Use this handy tool to compare two spreadsheets and quickly see the differences between them.
Do you have engineering spreadsheets that need to be under revision control? Typically documents like cable schedules, equipment lists, bill of materials (BOM) and instrument indexes require this. This spreadsheet is the answer to your problems. Simply change the working spreadsheet and click update and a rev with the changes highlighted will be created for you showing updates, adds and deletes.
Although Excel has this feature already included with it's 'highlight duplicates' function, sometimes a stand-alone list of the duplicates can come in handy.
