How to encode Data Matrix Barcodes using VBA in Excel?


The tutorial explains how to encode data in Excel using the Data Matrix Font Encoder VBA.

The Data Matrix Font Encoder VBA is included in:

Data Matrix Font and Encoder for Windows

Data Matrix Font and Encoder Package

Universal 2D Font Package

NOTE:
IDAutomation offers a 2D Font for Excel; however it does have some limitations. It is compatible with Data Matrix, QR Code, PDF417 and Aztec. Microsoft Excel may also be used as a data source for the font, as explained below.

Best Answer

1. Download and install a font package that includes Data Matrix. The package installs the necessary encoders. To generate barcodes directly in Excel, download and install the IDAutomation 2D XLS Font



2. Open Excel and set up the spreadsheet. In the example, data in column A2 will include the data to convert to the barcode. A formula will be written in B2 to produce the encoded data.

3. Minimize Excel and locate the VBA file named IDAutomation_DataMatrix_Macro.bas. The VBA is located in the Integration folder of the product download.

4. Maximize Excel and select the Developer Tab.

5. Select Visual Basic to enter the Editor.

6. To import the VBA file select File -- Import File then search for and select the IDAutomation_DataMatrix_Macro.bas.

The VBA file will appear in the Modules folder.



7. Select Tools -- References and search for the Data Matrix encoder; it will be named similar to IDAutomation Data Matrix and have a version number at the end of it. Choose OK.

8. Select File and choose Close and Return to Microsoft Excel.

9. In cell B2, enter the formula =EncDM and reference cell A2 to encode the data.

The encoded data for Data Matrix should appear as several alpha characters.

===================================================
To generate GS1 Data Matrix

=SUBSTITUTE(EncDM(A2,1,0,0), CHAR(13),"")

Setting the second parameter to 1 enabled ApplyTilde which allows you to insert ~1 before any Application Identifier (AI). Here is an example of A2 for GS1-Data Matrix:

(01)3456789012345 must be entered as ~1013456789012345

or using the Substitute function:

===================================================



10. Save the file.

HOW TO MAIL MERGE
To generate the barcode the encoded file must be used in a mail merge/data merge. Video Example of 2D mail merge. The only difference between the video and this tutorial is that the video uses the Barcode Add-In encoder and Data Matrix. Begin the video at 2:35.
Video Example

CARRIAGE RETURN ERROR
After merging the data into Word, a group of characters, such as _x000D_ or barcode
image, may appear at the end of the merged data. To resolve the issue, return to Excel and implement the SUBSTITUTE function.

Example:

=SUBSTITUTE(EncDM(A2), CHAR(13),"")
