PerfectXL Compare

User Cases & Application

On this page you will find a summation which aims to show the relevance and application of a spreadsheet compare tool based on the user tests we did while developing our spreadsheet comparison tool.

Overview of Changes

Overview of changes in a spreadsheet // PerfectXL Compare User Cases & Application

Our first use case involves a financial worker who wants an overview of the changes made between two versions of a spreadsheet. This could be for a variety of reasons, but is often done to check what has been changed by other people working in the spreadsheet. In many cases other users of the spreadsheet should only adjust data in the spreadsheet, and not formulas or structure. PerfectXL Compare groups differences into categories: data, formulas, and structure. These difference groups allow the financial worker to quickly see what has actually been changed in the spreadsheet.

Our findings show that PerfectXL Compare:

  • Gives a quick overview of all difference types
  • Reports only relevant information
  • Quickly finds well categorized differences
  • Is accurate
  • Is fast (94% of analysis under 1 second)

Our next use case involves a new secretary who has to use a large, complex spreadsheet models for agendas, hour plannings, and a variety of other in-house functions with the secretary is responsible for. She has been working with a particularly complex model for sometime when it suddenly stops working. The spreadsheet is so complex that it would be impossible to manually find the issue.
