Spreadsheet Reporting Breaks on Key-Person Risk, Not Bad Logic
Global – October 27, 2026 -- A Monday inventory consolidation that took 90 minutes of manual cleanup and cross-checking now runs unattended overnight, after its logic was moved out of one analyst's head and into documented workflow steps.
The case illustrates a point Alteryx makes in guidance for spreadsheet users: slow, error-prone reporting is rarely caused by wrong logic. It is caused by logic that exists only in formulas, tab names and one person's habits. The recommended fix is to capture the steps first and choose the tool afterward.
Key-person dependency, not formula errors, is the main failure point
Typical breakages include a renamed column that disrupts a position-based formula, a data set that outgrows a row limit, and two people editing one file so that one set of changes is lost. When the analyst who built the process changes teams or leaves, the successor must reverse-engineer each tab, often at report deadline.
