In my previous role, I was responsible for preparing and maintaining MIS reports and dashboards using Google Sheets. To ensure accuracy, I implemented a systematic approach that involved several key steps. First, I collected data from various departments and validated it to ensure its integrity. I used formulas, pivot tables, and charts to automate the reporting process, which minimized manual errors. Additionally, I regularly cross-checked the data against source documents and collaborated with team members to verify any discrepancies. This thorough validation process helped maintain the accuracy and reliability of the reports, which were crucial for supporting data-driven decision-making within the organization.
