To address the issue of incorrect data in an automated Google Sheets report due to a broken formula, I would first quickly review the formula to identify any obvious errors, such as incorrect cell references or syntax issues. If the problem isn't immediately apparent, I would use the audit trail feature to trace recent changes that might have affected the formula. Next, I would test the formula with a smaller data set to isolate the error. If necessary, I would consult with team members to get a fresh perspective or additional insights. Throughout this process, I would prioritize communication with stakeholders to manage expectations and ensure they are informed of the progress. By maintaining a methodical approach, I aim to resolve the issue efficiently while minimizing disruption to the workflow.
