First, are you talking about an actual form? Where data is submitted? If that’s the case, I would not suggest using ACF for this…instead I’d suggest using Gravity Forms or Formidable, both of which store form entries and have export functions that will give you exactly what you want, easily imported into Excel.
Perhaps if you can explain more about how you’re using ACF and why you’re exporting to Excel, I can help you come up with a solution.
