In this episode of M365.fm, Mirko Peters explains why clicking “Create app from Excel” feels smart for the first week and becomes a data‑integrity horror story once real users arrive. Excel isn’t a database — it’s a calculator pretending to be one — and the moment you plug it into Power Apps, Dataverse exposes every hidden flaw: no keys, mixed types, fake relationships, duplicate entities, orphaned rows, and silent corruption spreading behind the scenes.

WHAT YOU WILL LEARN
  • Why Excel feels fine for small tasks but fails as soon as Power Apps expects structure
  • The five failure patterns that quietly destroy Excel‑backed Power Apps: missing primary keys, mixed data types, VLOOKUP “joins,” multi‑purpose columns, and orphaned rows
  • How to design proper primary keys with surrogate GUIDs and alternate keys so imports, upserts, and automations stop duplicating or overwriting the wrong records
  • How to normalize data types (numbers, currency, dates, choices, lookups) so formulas, logic, and reports behave consistently instead of breaking on “weird” values
  • How to replace fragile VLOOKUP‑style relationships with real Dataverse tables and lookups for suppliers, locations, categories, and more
  • How to split overloaded “Status/Notes/Flags” columns into clean, governed fields so your app can actually validate, filter, and automate reliably
  • How to prevent and repair orphaned records by enforcing relationships, using “Unknown X” rows intentionally, and modeling delete behavior correctly
  • A practical 12‑step remediation path you can follow to fix your Excel model, move it into Dataverse, and stop your Power Apps from corrupting data in production
