Claude Code Workflow Automation for Non-Developers: Combine Excel Files, Create Reports, and Send Emails with Skills

I hand my work folder over to Claude Code without writing any code. It pulls together 12 Excel files from our branches, completes a one-page report, drafts 20 emails, creates an ad performance table and a meeting action-items list, checks the numbers against the originals, then saves the whole process as a skill I can run again next month with a single line.
