The purpose of creating barcode is clear which is for more than one items to be read later either for searching items or inserting an item into a system like supermarkets, then for this purpose, we need an application to generate barcode for us or online websites which is either it's not free or generate barcode one by one which takes a long time, Creating such a function by Microsoft excel or any kind of sheet apps is cheap and fast and accurate all you need to have is barcode font (you can find dozen of barcode font online) Microsoft Excel After you installed the font insert the serails or asset name or whatever you want to make it barcode into the excel column and apply this function to the cell next to the serial ="*"&[cell reference]&"*" then hit the enter and you have to change this cell font to the barcode font and apply this function to all coming cells.
