Code 39 can't show the "+" correctly

Hi, I need transfer some data into Code 39 in my Excel by use of Code 39 font. Everything works fine but the "+" sign. It can't be converted correctly. does everyone had the same problem before? One group of the data, e.g. is 35479A+.

You may have a try to find the "+" and replace it with the data you want. Also I suggest you to check the encoding scope and specification of the Code 39, it may helps.

Maybe you have wrong format for the cell, change it and see if it works. If it doesn't work, try other excel add-in

Plz ensure the data format of the cell, or it would turn some characters into others. If still wrong, recommend you to use add-in tool to implement this. Recommendation:Code 39 barcode generator add-in (http://www.businessrefinery.com/excel-barcode/code_39.html).

Have you input the start/stop characters "*"? Code 39 barcode is supposed to start and stop with the character.

Base on Code 39 ISO/IEC specification, "+" is encodable characters for Code 39 barcode. So, I guess this is the problem of your software. "http://www.barcodelib.com/barcode_fonts/font-code-39.html" is just one of many but I note it because it has a manual.

A Code 39 barcode symbology consists of five parts: left quiet zone, start character, data characters, stop character and right quiet zone. The asterisk symbol (*), used at the beginning and end of the data, performs as the start and stop character, and they cannot be transmitted by decoder.
In ur case, I think a Code 39 add-in for Excel will make things much easier for u.

This is might because the "+" is disabled automatically in Code 39 barcode generation process. Please check it for sure.

Thanks for your sharing.It is appreciated very much. And I wonder whether there are some differences between the .net barcode generator( http://www.keepautomation.com/guide/dotnet_barcode_generator.html ) I am testing these days and the one you mentioned above? Do you have any ideas about it? Or any good suggestion? Thanks in advance.
