Introduction to Excel Spreadsheet Power

ESP files speeds up large, complex and multi-worksheet Excel applications. If you are working with several linked worksheets, pivot tables, and Excel functions, ESP files will speed up calculations times substantially.


We thought the best way of demonstrating how ESP files improve Excel performance with a large application would be to show how a multi worksheet project of ours containing 450,000 calculation cells was optimised by a factor of 10 times faster calculation times.

When you install the Fast Excel files within ESP a new toolbar appears in your Excel (below) which adds these new calculation features: Worksheet and workbook run time microsecond clock counters button, Change the calculation sequencing, View and change the calculation options form, Set worksheet calculation enable/disable, Run diagnostic reports for selected worksheets (sample reports below), View the memory and pivot table cache usage report.

Step 1: Pre-optimisation. Our 450,000-cell workbook had an original calculation time of 51.4 seconds. (Cell H29 below = 51,483 milliseconds). The diagnostics shows a lot of wasted calculation time and it identifies the location of slow performing formulas and functions.

Step 2: Optimisation. Set the Reschedule routine to optimise to the fastest calculation sequences, identify bottlenecks and restructure Excel's calculation pathways. The calculation time for our 450,000 cells reduced to 6.7 seconds.

Step 3: Stop Excel churning. Excel will churn even the smallest spreadsheet calculations. Select which spreadsheet(s) to auto calculate when you press the return key. This stops Excel recalculating (churning) the entire workbook each time you hit the return key. In the demo provided the calculation time reduced to 1.66 seconds and recalculation to 0.61 seconds. Original calculation times for 450,000 cells were 51.4 and 40.7 seconds.

Optimisation procedures

Once your spreadsheet sequences have been optimised you will notice a great improvement in your Excel calculation speeds. Continue using ESP files to switch in and out of specific worksheet calculation modes to improve total performance.
