Weekly Timesheet Report + Pending Submissions Workflow Overview This workflow automates the entire weekly timesheet reporting cycle by integrating Salesforce, OpenAI, Gmail, and n8n. It retrieves employee timesheets for the previous week, identifies which were submitted or not, summarizes all line-item activities using OpenAI, and delivers a consolidated, manager-ready summary that mirrors the final email output. The workflow eliminates manual checking, reduces repeated follow-ups, and ensures leadership receives an accurate, structured, and consistent weekly report.
