How to remove duplicates in LibreOffice Calc

If you have a column or a table and you want to remove duplicate entries do the following (in LibreOffice Calc)

Select the range you want to filter
Data/Filter/Standard Filter
Name the column that you want to filter
Select a condition that is always true, like field1 = Not empty
Click on the button More Options, select Remove Duplicate, select Copy to and put the location of an empty cell
The whole selected range will be copied without duplicates at that new location.

    Thanks! This worked very well. On my LibreOffice (Macintosh version 3.3.2) the option is not "Remove Duplicate", but the more cryptic "No Duplicate".

    I'd say it's worth adding a bit of detail:

    when you select the data initially, just select the column you wish to filter by (you do not need to select ALL the data).

    same here, it was a 81000 rows sheet, but it only returned 16000, I know for sure that there were not 65000 duplicates.

    Just did the same thing, and the number of results is actually 16384\, which is 2^14, so I suspect it's a bug somewhere, where there is a loop that maxes out at 16 bit values.

    I couldn't get this to work at first. I did some experimentation, and the source of the trouble was this step:
    "Select a condition that is always true, like field1 = Not empty".

    That didn't work for me. Instead, I found success when I used this: "field" "does not end with" "!!!!!!". I don't know why Milo's suggestion didn't work...maybe it's a bug with my version (4.0.4 on Win7).

    Also, one clarification: If you have a spreadsheet, and your duplicates are in one column, say "B", be sure to highlight only column B...not all the columns when you follow the other instructions. This contrasts with MS Excel, where you highlight all the columns, and you pick the duplicate column from the wizard.

    Additional useful tip: if you want to check for duplicates in multiple columns: Say you have a table of customers, and you want to only delete identical customers with the same address and phone number, then you would use the Concatenate function to combine those three columns into a new column. Then, you eliminate the duplicates on that column. (You might have to replace the formulas with values using a paste special=>text...I can't remember if that step was required).

      Paul thank you I had the same problem on Win 8 (Version: 5.0.3.2 (x64))
      your way with
      "field" "does not end with" "!!!!!!"
      and
      highlight only column B...not all the columns

      I'd like to add to this: if you have multiple columns and are only filtering on one column, don't select the option to copy to a new range. It will only copy that column and exclude the rest of the data. Leave it deselected and it will filter the information in place.

    You have some Duplicate Files on your computer which hampers your memory space.
    Just use "DuplicateFilesDeleter" software.
    If you use this software you will be get comfortable.

    Thanks for this. Inspired me but not the problem I'm trying to solve. What I want is to finish up with only the results that appear only once in my first list i.e. I have this list

    aaa
    aaa
    bbb
    bbb
    aaa
    bbb
    zzz
    xxx
    yyy

    and what I want is only

    zzz
    xxx
    yyy

    Does any one have an answer?
