Excel Barcode Integration: Controlled Imports, VBA, and Safer Bulk Exports

Excel remains a practical front door for many barcode workflows even when it is not the system of record. The safest pattern is to let business users prepare rows in a controlled template, then run validation before any barcode assets are generated.

Sub FetchBarcode()
  Dim req As Object
  Set req = CreateObject("MSXML2.ServerXMLHTTP")
  req.Open "GET", "https://api.barcode-generators.com/v1/generate?data=" & Range("A2").Value & "&type=code128&format=svg", False
  req.setRequestHeader "Authorization", "Bearer YOUR_API_KEY"
  req.send
End Sub

Use spreadsheets for review and intake. Use structured validation and queued generation for production output.
