Generate Code 128 barcodes

How to generate Code128 Barcode in MS Excel spreadsheet

This implementation configures dynamic code 128 barcode encoding within spreadsheets by **registering the COM DLL interface** (cruflbcs_x64.dll for 64-bit systems or cruflbcs.dll for 32-bit environments) through an elevated command prompt. After **enabling all macros** inside the Excel Trust Center, open the VBA Editor using ALT + F11 to **bind the crUFLBcs Type Library reference** and import the barcodesoft.bas module. Data streams are then instantly converted using **native column formulas** like =Code128B(A1) and rendered visually by assigning the specialized Code128mHr barcode font typeface.

Step 1. Right click command prompt and run command prompt as administrator.
