iWork Numbers Barcode Tutorial for Mac

Using Self Checking Barcode Fonts with Numbers:

Self-Checking Barcode Fonts such as Code 39 (for numbers and/or uppercase letters) and Codabar (for numbers only) are the easiest to use in Numbers when encoding numbers and/or uppercase letters. Self-checking barcode fonts have built-in checking code so that it is not required to calculate a check character. These self-checking fonts may be printed or generated as a calculated field in Numbers easily. The following tutorial demonstrates how this is accomplished:

  1. To create a proper barcode with self checking fonts, a start character must be added to the beginning and a stop character added to the end of the data being encoded. This is referred to as the start/stop character, which is easily added F to IDAutomation's Code 3 of 9 barcode (for uppercase letters and/or numbers) with the asterisk character and Codabar (numbers only) fonts with an A as a start character and a B as a stop character.
  2. The start/stop character may be easily added to the beginning and ending of the data being encoded with a simple Numbers formula of  ="*"&CELL&"*" where CELL is the cell of the data being encoded in the barcode.
    • Fig. 1 Entering Code 39 formula.
      Enter the corresponding formula to encode the data correctly.
  3. After the formula is entered in the cell and copied down the column, select the correct barcode font for the cell and a symbol should appear. The cells may need to be sized to contain the entire symbol.

      Center the barcode in the cell to ensure the entire barcode appears in the cell.

  4. Print and scan the barcode(s) to verify the correct data is encoded. If a scanner is needed to verify barcodes, IDAutomation recommends the IDAutomation USB Barcode Scanner.

Combining Multiple Columns in a Single Barcode

Tabs and returns may be added using Extended Code 39 barcode fonts between cells by inserting "$I" (for a tab) or "$M" (for a return). For example, the following formula encodes a tab between cells A2 and B2:  ="*"&A2&"$I"&B2&"*"

Combine two fields separated by a tab.

Creating a Column of Barcodes in a Spreadsheet

IDAutomation barcode fonts provide an easy method of barcoding a column in Numbers. Code 3 of 9 barcodes are created in a Numbers spreadsheet in this example, with the IDAutomationC39 font that is included in the Code 39 Barcode Font Package. Codabar Fonts may also be used to create smaller bar codes when using numbers only. To use fonts other than Codabar and Code 39 on the Mac platform, refer to IDAutomation's Barcode Integration Guide for Mac.

  1. Barcodes are created in column B from the data in column A in this example. Enter the formula ="*"&A2&"*" in cell B2 to append the required asterisks to the text from cell A2:
    • Fig. 4 Entering Code39 Formula to barcode the cell.
      Enter the corresponding formula to encode the data correctly.
  2. Select the cell containing the formula and choose Edit - Copy. Highlight the entire column by selecting the rectangle labeled "B" at the top of the spreadsheet and choose Edit - Paste. The formulas may take some time to recalculate if the spreadsheet is large.
    • Fig. 5 Applying the Code 39 Font and formula to cells.
      Paste the formula into the entire column.
  3. With the entire column that contains the formula highlighted, select the IDAutomationHC39S font from the Code 39 Barcode Font Package or another appropriate font. The barcodes will then appear in the entire column.
    • Fig. 6 Select the Code 39 Barcode Font for the entire column.
      Select the IDAutomation barcode font.
  4. With the entire column that contains the formula highlighted, select the appropriate point size. In this example, 12 points is used. With the entire column that contains the formula highlighted, center the text so the barcode is in the center of the field. Size the column so it is wide enough to contain the barcode.
    • Fig. 7 Adjust the font size and center the barcode in the cell.
      Center the barcode in the cell to ensure the entire barcode appears in the cell.
  5. Print and scan the barcode(s) to verify the correct data is encoded. If a scanner is needed to verify barcodes, IDAutomation offers several USB Barcode Scanners. If there is a need to use barcodes smaller than 12 points, the IDAutomation Plug 'n Play USB Barcode Scanner dependably scans the Code 39 font when printed as small as 6 points.
