Code 128 Checksum Calculator Online Generator In Excel

The entered ASCII or Hex string will produce a checksum value that can be used to verify the checksum algorithm used by a particular device.

This tool is especially useful for interfacing with devices for IIoT and sensor-to-cloud applications.

Various parameter settings are available such as barcode size, rotation, resolution, image formats, text font etc.

Otherwise, confounding characters will appear after the barcode in Word.

Unfortunately, most of them are complicated or dont work in the later versions of Excel that most people use today.

Because of this, the generation of Code 128 barcodes is not as simple as typing the number sequence into a programme using a barcode font.

Follow these steps in order to create your own Code 128 barcode generator in Excel.

Create a table (making sure that you format as table ) with the following structure and headings.

Then paste the following code, which was written by Philip Treacy.

Now when you enter data into cell A2, a barcode should be displayed in cell C2 and so-on down the entire sheet.

I added conditional formatting via the following rule: D:D so that errors will be displayed.

Unfortunately people need a human-readable number string beside a barcode, which means copying both the barcode string and the number sequence used to generate it.

The other advantage with mail merge is that the barcode can be combined with other useful information on the label stickers in a manner which is efficient and unlikely to generate error.

Ive researched that a horizontal tab can be produced in code 128 using 9 or possibly 09.

Reason for this can include: the name does not begin with a letter or an underscore; The name containes a space or other invalid characters; the name conflicts with an Excel built in name or the name of another object in the workbook.

But its not generating a readable bar code 128 for some sequences like this one: 35160756642960000452590000879700000291361960.

There are minimum clearance zones and font sizes that are required for the bar codes to work.

I have also encountered this when its been printed too small.

There is a large space in the middle of my barcode when using the sequential values FP10001, FP10002, FP10003, etc.

In fields b2, c2, d2 I copied the formulas as directed and tje formulas is now what is now displayed in b2, c2, d2.

I did change the font for column C and it is displaying the formula as a barcode.

Ensure that your cells are formatted as a number then try re-entering the formulae again.

The fix for me was adding a space after the for each formula in B2, C2 and D2.

Hope that helps anyone trying to make this work Thanks Adam for the tutorial and Philip for the code.

Without formatting as table, tried to add a ABC123 in A2 and in c2 I tried giving Code128(Barcode) and also Code128(A2).

How about publishing the your example Word mailmerge doc as well.

Its best to change the font to any characters adjacent to the barcode mailmerge field to a normal text font.
