  • The ESP add-in provides an additional menu option (ESP) to Excel as shown below in Excel 2010 and similarly in earlier Excel versions.



  • The ESP add-in helps you build your spreadsheets rapidly with consistent conventions applied throughout.
  • You start with a standard three-sheet workbook as below.




  • Make your cell formatting consistent throughout with the use of AbleOwl ESP styles, which also reduces formatting time to a fraction (say, 25%) of what it would otherwise take.
  • Using correct techniques; quickly add subtotals with conventions applied.
  • Place entries that you don't want users to see / meddle with to the left of / above frozen panes. Instantly freeze and unfreeze panes.
  • Use a Range Names Manager to apply the ESP naming convention to range names and to manage names.
  • Click a few buttons to add crosschecks that cannot be missed.
  • Add further sheets with tab name and colour conventions that describe data flow throughout the workbook.
  • Easily include formulas for solving a variety of problems. For example, enter a combination of INDEX and MATCH functions to create a formula that overcomes VLOOKUP's weaknesses, such as not adjusting to a column insertion.
  • Rapidly build file-links that are robust to changes in the source file and structured to be easy to follow.
  • For workbooks of many sheets, at the click of a button insert a Menu sheet, which helps describe the structure and enables hyperlink navigation all around the workbook.


  • Record notes of changes made simultaneously in comments and on a sheet named Changes.
  • So that you can check all crosschecks at a glance, insert a Crosschecks sheet that reports on all crosschecks in the workbook.
  • Quickly apply validations so that, for example, in certain ranges, only numbers can be input. Similarly, apply date, time and text validations.
  • At the click of a button, password-protect a whole workbook to prevent unwanted changes.
  • With a few clicks, include buttons that allow users to insert or delete rows at specified places on protected sheets.
  • Include many other automations such as one for placing data into reports from a database sheet.
  • Drill-down on SUMIF, VLOOKUP, INDEX-MATCH, array formulas, DSUM and much more.
  • Take advantage of various tools for: filtering, synchronising sheets, changing case, tracing links, checking for errors, printing multiple reports, managing sheets, selecting like-cells, …
  • Include your applications in an Applications Manager so that you can open any application quickly without the need to search through folders.
