Duplicate Finder & Deleter Improvements

The latest release of the Duplicate Finder & Deleter is 6.1.  It is Excel 2007-2019 and Office 365 compatible. 

Latest improvements:

  • Nov 18, 2018 - product review and improvements.
  • Sept 22, 2015 - Released Excel 2016 compatible version
    • It is also backward compatible with Excel 2007-2013.
  • June 24, 2014 - Fixed an Excel bug with dialogs not always appearing in the center of the Excel window if the user has two or more monitors.
  • May 5, 2014 - Minor change to the find duplicates in a block of cells feature
  • Mar 3, 2014 - Fixed a problem with comparing two lists and extremely few matches occurring
  • Jan 16, 2014
    • Speed improvement
    • Minor menu improvement
  • Jan 13, 2014 - Modified so that when asked for the top row of the data range, the user only has to type in the row number as a number (vs for example, 2:2, or having to scroll and select the row)
  • Sept 2, 2013 - Added a check of the data on a worksheet to see if has been converted to an Excel data list, and if so, advise the user to convert back to a normal Excel range before using the add-in.  A bug in Excel requires this. As few users use Excel data lists, few are impacted.
  • May 27, 2013 - Minor installation improvements
  • March 7, 2013 - Released Excel 2013 compatible version with ribbon menu for ease if use.  Available all the time with just a click.
  • Sept 4, 2012 - Fixed a problem with the feature to copy first and unique occurrences to a new worksheet.
  • Aug 21, 2012 - Modified so that ascii character 160, which looks like a space, is treated as a keyboard space, which is ascii character 32.  Ascii character 160 is normally only used in HTML pages as a non-breaking space to align text.  It should not part of computer generated data or downloaded data.  One of our customers had data that had ascii 160 in one list and regular spaces in another list, resulting in no duplicates being found as the characters were different.
  • Mar 26, 2012 - Minor title and wording changes
  • May 26, 2011 - Modified to insure that user does not accidentally pick hidden columns when selecting comparison columns.
  • Apr 6, 2011 - Added in a top data row confirmation if the first data row is below row 5. This was done to help insure that the user correctly picks the first row of data and doesn't accidentally pick a starting row below the top of the data.
  • Dec 14, 2010 - Modified the option on find 1st occurrences and duplicates to mark both versus just duplicates.
  • Nov 11, 2010 - Minor menu changes.
  • June 1, 2010 - Release 4.0
    • Excel 2010 compatible version

  • Nov 9, 2009
    • Improved the compare two lists feature to have more options

  • Mar 11, 2009 - Modified so that last set of columns used to check for duplicates can be re-selected with one click. Also modified the options to make coloring of duplicates an option.
  • Jan 26, 2009 - Added a second approach to unhidden rows and columns in case the conventional approach to unhide does not work.
  • Jan 17, 2009 - Modified the message on hidden rows and columns to be clearer and to give the option to unhide hidden rows and columns versus having to do so manually.
  • Jan 14, 2009 - Modified to use alternate input boxes so that users (a few) with some problems in their worksheets are able to use.  These users, because of problems in their worksheets, were not able to use the default input boxes.
  • Dec 22, 2008 - Improved the help file, minor menu improvements, and modified the search two lists
  • Nov 14, 2008 - Modified the feature to search a block of cells to have options on coloring the first occurrence if duplicates are found.  Also, hidden cells are no longer checked.

  • July 3, 2007 - Digitally signed our installation exe and add-in using a software code signing certificate from Thawte to add another level of security and confidence in our products.  It allows users to maintain macro security on the high security setting in Excel and still run our add-ins.
