License / Versions

What do I get when I buy the full version?

However, you won’t get access to the underlying source code and VBA macros.

The purchase process is handled via Clicking on the Purchase button will guide you to the site.

The software is the same as the trial version. Only the trial version expires after 7 days after the first usage. You can redownload the trial version any time and enter your purchased license key again.
Does your add-in still get updated and does it support the newer versions of office?
Yes, we still update Professor Excel Tools (the history is available when you scroll down). And yes, it works with newer versions of Excel, such as the Office 365 subscription. We are heavy users ourselves so we’ll try to keep it working.
However, we don’t legally guarantee anything. You get the add-in “as-is” and can’t guarantee “eternal support”. That’s mainly because we also rely on Microsoft and their specifications. Also, please make sure to test the trial on your local computer.
So, in a nutshell: Yes, as of now, it should work with the newest versions and we try to keep it that way.
What is the difference between the trial and premium/full version of Professor Excel Tools?
Functionally, there is no difference between the free trial version and the premium / full version of Professor Excel Tools. The trial is fully functional. Actually, it’s the same installer and source file. So, if you’ve downloaded the free trial, there is no other change required once you’ve purchased the full version.
The trial version only works for 7 days. After that you have to enter a license code.
There is, however, one exception: The Professor Excel built-in formulas (such as “=PROFEXSheetName()”) still work in the trial version after it has expired.
One more comment: Please test the trial before purchasing the premium / full version.

Version 1.4, release date: February 25, 2017

Bug fixes and performance improvements.

Version 1.3, release date: February 14, 2017

We are excited to announce a major update introducing many new and improved features:

    Applying is even easier: Select cells you want to format and click on one of the Quick Format Buttons.
  • Clean formulas: Often, formulas can get long and messy. Use the clean formula function to remove all “=+” in the beginning of a formula and remove worksheet names, if you link to the same worksheet.
  • Export Manager: Export one or more worksheets to a folder. You can define one input variable to change each time.


  • Calculate selection, force to number, insert IFERROR and ROUND now work on array formulas.
  • When using the Quick Share Buttons you can now set (within the settings) if you want to remove INDIRECT formulas as well. Cells containing INDIRECT formulas will be converted to hard values.
  • Layout Manager: Change the direction of outlines/groupings.
  • Swap two cells: You can define within the settings, if other cells linking to your two swapped cells should adapt or not.
  • Force to number: Works on formulas and array formulas. It also uses your favorite number format (defined within the settings). Also, we’ve further improved this function.
  • You will more often see the progress bar. This is especially useful when applying changes to many cells at the same time.
  • Name Manager: Shows the total number of names and the number of selected names.
  • Insert IFERROR and ROUND: More reliable with long formulas.
  • Improved update function.
  • Compare sheets: Sheets will be converted to hard values before the comparison.
  • You can now clear the status bar info within the settings.
  • Improved layout.
  • Many more minor bug fixes.

Version 1.2, release date: June 26, 2016

We are excited to announce a major update introducing many new and improved features:

New features:

  • “Reduce File Size” now shows you the size of each worksheet. You can then select which worksheet you want to reduce.
  • New function: “Name Manager”. The built-in name manager only shows a small portion of the names in your workbook. With our new name manager you will see all named ranges and you are able to remove them separately.
  • We removed the function to swap comma and point (usually people use the function “Force to number” instead). Instead, we introduced a function to swap two cells. The best part: any cells directly linking to one of the swapped cell will automatically adapt.
  • New function: “Remove Conditional Formatting” rules but keep the format. Just select the cells with conditional formatting and press the button “Remove Conditional Formatting”.
  • This function is very exciting: press Ctrl + Alt + c on the keyboard for copying the current cells. You can then use one of Professor Excel Tools paste functions or the normal Excel paste options. The best part: copy the last range again by pressing Ctrl + Shift + c.
  • Many new formulas:
    • PROFEXAuthor: Insert the name of the author.
    • PROFEXDateCreated: Insert the date on which the workbook was created.
    • PROFEXDateLastSaved: Insert the date on which the workbook was last saved.
    • PROFEXFileSize: Insert the file size of the current workbook.
    • PROFEXFolderName: Insert the folder name of the current workbook.
    • PROFEXLastSavedBy: Insert the name of the person who last saved the workbook.
    • PROFEXNumberOfHiddenWorksheets: Insert the number of hidden worksheets.
    • PROFEXNumberOfWorksheets: Insert the total number of worksheets.
    • PROFEXWorkbookPath: Insert the workbook path.


  • Insert formula: when you insert a PROFEX formula through the insert formula window which can also be created with built-in formulas, Professor Excel will insert the real Excel formulas instead of PROFEX formulas. That way, users without Professor Excel Tools won’t see error messages.
  • We have moved the “Workbook Info” button to the Info section.
  • Improved sharing buttons.
  • Minor bug fixes and performance improvements.
