First off, it's necessary to choose the source and target workbooks, which is easy with the drop-down lists that contain all recently opened items. Or click on the special icon to browse for the needed name. As soon as you pick the Excel files to compare, they are placed side by side so you easily see all the differences. Synkronizer works with all types of files supported by Microsoft Excel.

On step two you select the source and target worksheets. It's possible to include protected, empty or hidden sheets, match them by name, index or code name. You can specify how the worksheets should be paired - automatically pick all or only the first sheets with the same name, or choose them manually. Just click on the icon with a double arrow to add all matching worksheets automatically.

Step 3 offers to choose among the following Excel compare options.

  • Compare as worksheet. To use this option, please make sure that your data tables have the same number of rows and columns which have the same location in both sheets. Also your worksheets mustn't contain any new or deleted rows or columns. If this is the case, your files will be compared using the "1 on 1" method which means that the add-in will detect only cell differences.
  • Compare with link options. Compare the rows and/or columns by linking cells, columns and rows 1 on 1.
  • Excel compare as database. If you choose this radio button, your worksheets must have a database structure. This means they need headers and one or more key columns with unique identifiers to be used for matching. This option allows to find duplicates and merge or consolidate your worksheets.

Step 3 offers to choose among the following Excel compare options

Choosing to compare Excel files as database, you will get a new tab with settings. It allows you to select one or more columns with key values that will be used for comparison. There is also an option to define if the headers consist of one or more rows. It's really helpful if you have a hierarchy of header rows.
Configure database settings

The following additional options let you fine-tune the search for the database setting.

  • Relaxed keys. By default the add-in uses case-sensitive matching. Thus it will see John and JOHN as two different values. Excess spaces may also be an issue. Choose the Relaxed keys checkbox to ignore the differences in spaces and upper/lower case.
  • Sort records. The records will be sorted by key values.
  • Group records. The data are grouped by linked records, new or deleted values, additional matches, and duplicate rows.
  • Add SynkID column. Insert a special column that will show the status of the records in your worksheets. You will easily spot duplicates, missing rows and records that are different in two tables.

Having selected the worksheets to match, let's look at the ribbon under the Select tab to define additional Excel compare settings.

Additional options to compare data in Excel

Under the Select tab, you can find the Compare and Tools groups with additional options that let you compare worksheets in Excel exactly as you want.

If your tables contain comments or named ranges, you can find any changes and unify the sheets using the Content menu.

The filtering function enables you to reduce the number of differences that will be found and displayed. Just click Enable filters and choose the filter(s) which you want to apply.

  • When you compare two files in Excel, you can choose to ignore case, spaces, different format of identical numbers, constants, formulas, hidden columns and rows. If your tables contain different formulas that result in the same value, you can choose to see such results as different.
  • It's possible to choose a deviation to show how tightly the values in the dataset must be bunched around the mean value. For example, if you enter 0.5, then only deviations greater than 0.5 will be shown.
  • One more really helpful feature is defining equivalent values. Suppose, you have 2 worksheets with survey results. In one sheet yes is expressed by the plus sign and in the other - by the word true. You can specify that + is the same as true and have your Excel worksheets compared in an instant.

Choose the filters settings

If necessary, you can automatically generate a repot with all the differences found. You can even choose a hyperlinked report where each difference has a link to the corresponding difference in your table.

  • Some of the columns and rows exist only in the target or source sheets.
  • There are also duplicate records that should be deleted or processed further.
  • The add-in has found differences in values ​​and formulas.

Click on the difference value to see the list of dissimilarities on the pane and easily navigate to them. Here you can also insert or delete the selected differences. If I select the Columns differences value, I can clearly see that my source table is missing two columns that my target table contains. I can use special buttons to insert just one or both columns to my source sheet, or delete the columns from the target list. Once the columns or rows have been copied, they are displayed in red.

Just alike we can transfer or delete duplicates, update our sheets with formulas and comments, fix incorrect formatting.

  • Sort by column. The differences are sorted by columns and then by rows.

To avoid selecting files and worksheets, and changing the settings again and again, you can save any comparison process as a separate project. Just click on the Project tab to create a new project, open, save or reload it. Here you can also see the list of recently opened entries and configure settings for each saved file. In addition it's possible to load, save and reset your preferred settings like contents, formats, filters, report, highlighting and outline.

The option to highlight the differences with color is great. You can change the standard color scheme and choose your own theme to display the changes in your worksheets. The colors can be reset to the original if necessary.
