Uncovering the Power Apps Lie: Why Excel Isn't as Seamless as You Think
Welcome back, fellow creators and app builders! If you have been following our podcast journey, you know we love diving deep into the realities of the Microsoft 365 ecosystem. In a recent episode, we tackled a massive misconception that trips up creators of all skill levels. If you missed it, you need to listen to our breakdown on Fix Power Apps Excel Data Limits with Dataverse. Today, we are expanding on that exact topic.
Many creators fall into the trap of believing Excel is an effortless data source for Power Apps. It is quick, familiar, and practically everyone has a spreadsheet lying around that looks like a ready-made database. But is it really that simple? In this post, we are breaking down the hidden limits, file size restrictions, and performance bottlenecks that can disrupt your application. Let us pull back the curtain on the "Power Apps Lie."
Excel Limitations

Data Size Issues
Excel can hold up to 1,048,576 rows per worksheet, but this number does not guarantee smooth performance when you use Excel data in Power Apps. The Power Apps Excel connector can handle tables with up to 500,000 rows if you use a unique column instead of auto-generated IDs. However, practical limits appear quickly. The maximum file size for the Excel connector is 25MB, and Power Apps throttles requests at 100 calls per minute. These limits affect how much data you can load and manipulate.
| Limitation Type | Description |
|---|---|
| Maximum File Size | Excel files connected to Power Apps must stay under 25MB to avoid errors and slowdowns. |
| Default Record Limit | Power Apps shows up to 500 records by default, but you can increase this to 2,000 records. |
| Delegation Issues | Functions like Filter and LookUp cannot process more records than the set limits, causing incomplete data retrieval. |
When you try to work with large Excel files, you may see error messages from the Excel connector. The connector struggles with bigger files, especially if they lack unique ID columns. Delegation problems arise when Power Apps cannot query all the data, limiting your app’s functionality. These issues often lead to frustration and poor user experience.
Complexity of Structures
Excel works well for simple tables and calculations, but it lacks the structure needed for complex data relationships. You might have multiple sheets with related data, but Excel does not enforce relationships like databases do. This situation leads to:
- Mixed data types in columns, which confuse Power Apps.
- Missing primary keys, making it hard to link records reliably.
- Orphaned records that cause data integrity problems.
You may try to mimic database relationships using formulas like VLOOKUP, but these do not translate well into Power Apps. The app expects clear, consistent data models. Without them, your app may behave unpredictably or fail to scale as your data grows.
Collaboration Challenges
When multiple users edit the same Excel file stored in OneDrive or SharePoint, collaboration issues often arise. You might notice:
- Sync problems where changes made by one user do not appear for others immediately.
- Inserted columns or new data sometimes fail to show up or display incorrect values.
- Version conflicts that cause confusion about which data is current.
Managing different versions of the same Excel file becomes a challenge. Although Excel’s Version History feature helps by allowing you to view and restore previous versions, it does not solve real-time collaboration problems. Manual data entry increases the chance of mistakes, especially during bulk updates. Multiple users editing the same file can lead to data discrepancies and require strict version control protocols.
Power Apps tries to reduce data corruption risks by offering controlled access and real-time updates. However, when you rely on Excel as your data source, these protections have limits. The Power Apps Lie often hides these collaboration pitfalls, making you believe Excel integration is seamless when it is not.
Note: Due to these data size, structure, and collaboration limitations, Excel is not the best choice for building scalable and reliable Power Apps. Consider alternatives like SharePoint lists, Dataverse, or SQL databases for better performance and data integrity.
