Hi Kumaid,
I assume you have a very long list of ingredients in an Excel spreadsheet. This is open on a computer in your warehouse which has a simple barcode scanner attached to it.
To save the receiver some time in locating the row with the ingredient being received, you would like to be able to scan the barcode and be taken straight to that row in the Excel spreadsheet.
Correct me if my assumptions are wrong, but this is what I am understanding from your post.
Barcode scanners are typically set to emulate keyboard input. So at the simplest level, you could click CTRL & F in Excel, scan the barcode and hit enter to be taken to that row.
Or, you could have a cell at the top of the screen which is used as the barcode input, and when that is updated a Macro could fire to essentially do the same thing as above.
In summary what you may be attempting to achieve is very straight forward.
HTH.
