How To Remove Duplicate Entries in OpenOffice.org Software

OpenOffice.org offers an open source option for users that is very similar to Microsoft Office and is compatible with Macs. Although Microsoft Office offers software solutions for Mac users, there are times that the software is unavailable. OpenOffice.org is a completely free download that offers programs that are similar to MS Word, MS Excel, MS PowerPoint as well as drawing programs and an extensive database creation program. It is compatible with the Microsoft software with the option to save in several different formats. Despite the similarity, there are a few differences with functions that are used on a regular basis. One of the functions that I ran into is how to remove duplicates from a spreadsheet. Although the process is very similar to the older '93 version of the MS software, the newer programs have the function programmed in as a one-click function.

This tutorial will show you how to successfully remove the duplicates from a calc documnt (spreadsheet) in OpenOffice software.

1. Select the data column that you want to remove the duplicate data. In this tutorial we will be removing the duplicate email addresses. You can select the entire column by selecting the letter at the top of the column (in this case 'c').

2. Once the data is selected go to "data" -> and select "filter".

3. You will then have a new dialog box pop up with a few options. In the "field name" the appropriate title matching your data. If you selected just that one column, it should default to the correct column.

In "value" choose "-not empty-.

Choose "more options" and the dialog box will open up with the duplicate options. If you do have column labels (headings) keep that checked. Then check "no duplication". Choose "OK".

At this point you just 'hidden' the duplicate entries, you have not yet deleted them. You can see this by your line numbers, you will see that some numbers are no longer showing.

To delete the entries is as easy as copying and pasting. Select all of the fields (you can do this by choosing the cell in the far upper left corner between the cell numbers and the headings). Copy all of the content, open a new calc sheet and then paste. Save the spreadsheet and you will see that all of the numbers are now in order again.
