  • Sort data. Sorting data can improve Excel’s processing speed. Arrange your data in a structured manner. Make it easier for Excel to navigate and compute.
  • Avoid using the entire column/row as a reference. Refrain from referencing entire columns or rows unnecessarily. It can lead to excessive calculations, slowing down Excel.
  • Enable Manual Calculation mode. Switching to manual calculation mode prevents Excel from recalculating formulas. You can update when needed, reducing the frequency of calculations and boosting performance.
  • Limit conditional formatting. While conditional formatting enhances visual appeal, excessive use can impact Excel’s speed. Limit the number of rules and the cells they apply to.
  • Always check for updates. Updating Excel ensures you have the latest performance enhancements and bug fixes. Keeping your software current can contribute to a smoother Excel experience.
  • Always create backups. Creating regular backups is important. In the event of unexpected issues or data loss, having a backup ensures you can restore your work. It also prevents unnecessary lag-related setbacks.
