The problem

Agents can’t help with real work if they only see plain text — customers live in Word and Excel and expect edits back in the same file.

Approach

A .NET/OpenXML microservice for programmatic read/write of Office documents — the grounding layer that ingests customer files and writes edits back as tracked changes, preserving the original formatting.
