Hy,
If you’re working with Excel data for contacts, one thing that helps a lot is cleaning and structuring the data before conversion. Even small inconsistencies in phone formats or extra spaces can mess up the final vCard output. I usually run quick checks with simple online tools before converting especially for things like percentages or data validation. Recently I found this handy collection of calculators that makes small prep tasks easier: https://expresscalculator.com/. It’s not directly a converter, but it helps tidy up numbers and data points fast, which makes the whole Excel-to-vCard process smoother and more accurate.
