I need a clean, scalable Google Sheets workbook that automatically generates and stores UTMs for three URL groups I will supply—website pages, email-campaign links, and social-media posts. Every link you create must include the standard parameters campaign source, campaign medium, and campaign content, wrapped in a clear, consistent naming convention so the data remains easy to filter once it hits Google Analytics. Here is the flow I have in mind: • Import my master list of URLs into a dedicated input tab. • Generate UTMs on a second tab via formulas or Apps Script so edits propagate automatically. • Copy the finished links into a tracker tab that is sorted, color-coded, and ready for additional campaigns. The file should arrive free of hard-coded data (aside from my URLs) so I can duplicate rows or tabs without breaking anything, and your cell references need to be absolute where appropriate. Once the core sheet proves stable I’ll reuse it across brands, so logical structure and tidy documentation in cell notes are essential. Hand-off is complete when the sheet passes these checks: 1. All provided URLs return a correctly formatted, working UTM. 2. Changing any parameter value updates every associated link instantly. 3. I can add a new row, paste a fresh URL, and watch the new UTM populate without extra steps. If you’ve built marketing dashboards or GA4 tagging frameworks before, that context will help, but the real priority is a rock-solid Google Sheets build. Let me know your estimated turnaround and any clarifications you need on field naming.
