The latest YouTube video from Mynda Treacy of MyOnlineTrainingHub showcases a common frustration: using a habit tracker built in Excel on a phone is often awkward. In the clip she explains that panning, zooming and trying to tap small cells makes simple tasks like ticking a checkbox feel clumsy. Consequently, she demonstrates how she partnered with Zite to convert a 30-minute, 20-function spreadsheet into a mobile app that is easier to use on the go.
Mobile Excel has improved, and features such as mobile editing, cloud storage access, and new touch-friendly modes aim to help users work away from a PC. However, the grid layout and desktop-oriented controls can make routine actions slow on a small screen, especially when a workbook includes many formulas or heavy formatting. Therefore, while Microsoft continues to add mobile-friendly features like Cards View and the consolidated Microsoft 365 Copilot app, real-world usability still depends on the workbook design and the task at hand.
Treacy walks viewers through planning the app, showing a finished interface that reduces clutter and puts the most-used controls front and center. By transforming table rows into mobile-friendly inputs and simplified views, the resulting app lets users check off a daily task with one tap instead of juggling sheet navigation. Furthermore, she highlights that the conversion keeps the workbook logic intact while adding a cleaner user interface for routine use.
Converting a spreadsheet into an app improves usability for frequent, simple interactions, but it introduces tradeoffs that users should consider. For instance, the app approach can limit access to advanced Excel features and may add reliance on a third-party service for hosting and syncing data, which raises questions about performance, version control, and privacy. Moreover, preserving complex formulas and ensuring that the converted interface reflects changes correctly requires careful planning and testing before rolling the app out to daily use.
Despite the appeal of a dedicated app, some tasks are still better handled inside Excel on a desktop, especially when a workbook uses complex analysis, extensive formatting, or very large datasets. In those scenarios, the desktop environment provides better visibility, quicker recalculations and more robust tooling for debugging formulas. Consequently, Treacy recommends assessing the real needs of the task: if you only need to record simple daily items, an app is likely better, while heavy analysis should stay on desktop.
Treacy emphasizes planning the app before building it and testing the converted interface on an actual phone to catch usability issues early. She also advises thinking about data flow: choose where the source workbook will live, how updates will sync, and who will maintain the app’s logic over time. Finally, she notes that adding AI analysis or automated summaries can be powerful, but it increases the need to validate results and to ensure users understand how conclusions are generated.
The video touches on newer mobile capabilities such as using AI to analyze data and presenting table rows as focused cards for easier editing on phones. These tools reduce friction for casual review and quick checks, and they reflect a broader strategy to make mobile interactions more conversational and task-focused. Nevertheless, integrating AI summaries or card-based edits introduces new challenges in accuracy, data interpretation and user trust, which organizations should manage through transparency and testing.
In her verdict, Treacy concludes that converting certain spreadsheets into apps is a practical path when usability on phones is the priority. However, she balances enthusiasm with caveats: converting is not a universal fix, and it works best for narrowly scoped tools like habit trackers or daily checklists rather than for full-featured analytical workbooks. Therefore, users should weigh convenience against maintainability, data control and feature need before deciding to convert.
Organizations should consider a small pilot when moving critical spreadsheets to app form, because pilots expose maintenance issues and data flow problems early. Meanwhile, individuals who frequently need a simplified mobile interface will likely appreciate the smoother experience that an app provides, while power users may prefer to keep complex tasks on desktop. Ultimately, Treacy’s demonstration shows a pragmatic route forward: use the right tool for the job while planning for the tradeoffs involved.
