the azure billing report is a disaster; they seem to be slowly fixing it though. The line items are tricky and usually not super human friendly, multiple billable resources roll up to single items with weird quantities in some instances, if you have mixed ARM and ASM resources only the ARM stuff in your usage report will have data for tags (cause there's no concept of inheritance from parent resource group), ARM and ASM resources have different formats for some common fields, and tons more I've repressed from memory. If you have an EA agreement, half (or more?) of the billing report interfaces don't work. If you have to use the EA portal due to an EA agreement....lets just say within the past year they have been through some rough periods of random undocumented format changes, magically disappearing billing reports for a few hours at a time, random intermixed windows and linux style line endings in the same file, periods where they are DAYS behind your actual usage, etc... Source: I wrote a infrastructure inventory and billing/usage aggregation system that normalizes data from Azure, AWS, and vCenter to help our company easily track spending by service, tags, etc... across all of platforms where we have a presence.
