🚀 Boosting Efficiency with Formula Optimization! 🚀 In my current role, I faced a challenge with our Annual Performance Review (APR) process. The formula I initially wrote was causing significant slowdowns: =IFERROR(XLOOKUP($A3 & TEXT($J$1, "mm-dd-yyyy"), DUMP!$D:$D & TEXT(DUMP!$AD:$AD, "mm-dd-yyyy"), DUMP!$AE:$AE), 0) This formula worked, but it was making my system incredibly slow due to its complexity and the large dataset it was handling. Determined to find a better solution, I sought assistance and discovered a more efficient approach: =ARRAY_CONSTRAIN(ARRAYFORMULA(IFERROR(INDEX(DUMP!$AE:$AE, MATCH($A3 & TEXT($J$1, "mm-dd-yyyy"), DUMP!$D:$D & TEXT(DUMP!$AD:$AD, "mm-dd-yyyy"), 0)),0)), 1, 1) This new formula, suggested with the help of ChatGPT, dramatically improved the processing speed of our APR system! It’s a great example of how leveraging AI and innovative thinking can lead to substantial performance enhancements. 💡 Key Takeaway: Never stop exploring new solutions and tools. Sometimes, a little optimization can make a huge difference in productivity. #Efficiency #DataProcessing #ExcelTips #AI #Productivity #ContinuousImprovement #Innovation #PerformanceReview
