Excel as a data source is both really fast and highly prone to mistakes. To help avoid mistakes, I usually do the following: 1) Limit the number of users who can access the spreadsheet. 2) Password protect the sheet and lock cells I do t want touched (headers, etc.) 3) Limit copying and pasting as it may transfer cell data types and break. I find this helps, but isn't perfect. Fast is good for certain things. I avoid using Excel as a data source as much as possible, but sometimes you just need something really fast and this is a great solution.
Excel loaded to Power BI is really easy ... but also easy to mess up. Reasons my report has broken from Excel: -Text in Numerically formatted Columns -Whole new format of data -Column order rearranged -Changed Column names -Duplicate ID values -Removed Columns -Tables moved -Empty rows But sometimes it's inevitable, And Excel just happens to fit the needs. 2 ways to prevent Excel breaking your Power Bi report as often: - Don't use Excel, use dynamics or sharepoint lists (similar but more controlled) - Protect the cells (like header names) so they can't be altered.
