How to Fix Excel Not Responding?

Fix 1: Reduce Workbook Complexity

Reducing workbook complexity is a crucial step in resolving the ‘Excel not responding’ issue. This involves several key actions aimed at streamlining the data and functions within Excel. Simplifying your workbook not only enhances performance but also makes your data easier to manage and understand.

Start by examining the size of your Excel file. Large files often become unwieldy and slow to process. If your workbook is excessively large, consider splitting it into smaller, more manageable files. This can be done by organizing data into separate workbooks based on categories or time periods. For example, if you have a file with several years’ worth of data, divide it into individual files for each year.

Next, focus on optimizing formulas. Complex and array formulas, especially when used extensively, can significantly slow down Excel. Replace complicated formulas with simpler equivalents whenever possible. For instance, instead of using multiple nested functions, try breaking them down into separate steps. Additionally, avoid volatile functions like INDIRECT and OFFSET as they recalculate every time there’s a change in the workbook, which can cause performance issues.

Conditional formatting can also contribute to workbook complexity. While useful for data visualization, excessive conditional formatting slows down Excel. Review your use of conditional formatting and remove any that are not essential. Keep formatting simple and avoid using multiple rules on large data ranges.
