Excel is the spreadsheet. ## If you have never used it If you build interactive reports and publish them to app.powerbi.com, this is Power BI Desktop, not Excel.

A .pbix file will not open as a full report in EXCEL.EXE. ## What is it used for? **Model and visualize data** Queries, a model, and report pages. A single Excel sheet is not this semantic model. **Publish to Power BI service** Desktop authors. The service hosts. Excel Publish is a different path. **DAX measures** Measures live in the model. Excel has its own DAX in Power Pivot. The files are still different. ## Who is it for? - Analysts who publish to a Power BI workspace - People whose .pbix will not open in Excel - Anyone who should not install Excel hoping to get PBIDesktop.exe ## Current status Actively developed. Microsoft ships a monthly Desktop build. This article is the Windows designer, not the service admin portal. ## How old is it? Power BI Desktop launched in 2015 out of Power Pivot and Power Query ideas that started in Excel. It is a separate app. Excel remains EXCEL.EXE. They share mashup DNA. They are not the same executable. ## Versions Major channels first. Exact build numbers are not all verified here. Power BI Desktop (monthly) Power BI service Report Server ## System requirements Values follow the publisher's public guidance. Workload still changes the real need. ### Minimum | Operating system | 64-bit Windows 10 or Windows 11, per Microsoft for Power BI Desktop | | ---------------- | ------------------------------------------------------------------- | | RAM | Microsoft asks for several GB. Large models want more | ## Resource profile - **CPU demand**: Follows what you open inside the app **RAM demand**: Follows documents, tabs, or libraries ## Installed processes These executables belong to this product when it is installed. | PBIDesktop.exe | Power BI Desktop | | -------------- | ---------------- | ## Startup components Power BI Desktop starts when you open a .pbix. It should not start with Windows. ## File locations | Typical install | C:\Program Files\Microsoft Power BI Desktop\bin\PBIDesktop.exe | | --------------- | -------------------------------------------------------------- | ## File formats PBIX, PBIT ## Common problems ### Desktop missing from an Office install Microsoft 365 that includes Excel still does not place PBIDesktop.exe. Download Desktop separately. ### Publish fails without a service account Desktop can save a .pbix locally. Sharing to a workspace needs a Power BI account and a capacity your admin allows. ## Getting unstuck ### Install from powerbi.microsoft.com/desktop or Microsoft Store Do not download PBIDesktop.exe from a filename mill. Microsoft documents both channels. ### Open file location if Excel and Desktop are both running EXCEL.EXE is the book. PBIDesktop.exe is the report. Ending one does not save the other. ### Update Desktop monthly if a visual will not load Service visuals can require a current Desktop. That is not an Excel channel update. ## Alternatives Excel, Tableau, and the Power BI service overlap. Excel is the sibling this article is not. ## Official help and downloads Start with the vendor.
