OpenOffice.org Spreadsheet is most often found on 1 operating systems. The file will work on Windows systems, unfortunately not on others.

LibreOffice will apply when it is not possible to use Apache OpenOffice.

How to open OOS file?

An often recurring problem with OpenOffice.org Spreadsheet is that OOS is not associated with the correct program file. This causes the file OOS to open by system applications not designed for this purpose, or to display a message that there is no associated program. How to solve such a problem?

The first thing you should do is just "doubleclick" on the OOS file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.

Step 1. Install Apache OpenOffice

In this case, you should first verify that the Apache OpenOffice application is installed on the computer. To do this, enter the name Apache OpenOffice into the system search engine. If we do not have this program, it is worth installing it, as it will help you automatically associate the file OOS with Apache OpenOffice. Below you will find a list of applications that support OOS files.

Programs to open OOS file

Remember to download programs supporting OOS files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of Apache OpenOffice with OOS files

However, it may happen that the application itself does not cause the OOS file to open in the Apache OpenOffice application, but you can set it manually. The association can be created using the drop-down list available by right-clicking on the file and selecting Properties. The displayed window will contain information about the program that supports this type of file. Using the "Change" button we can set the program to handle this type. It may happen that in the next window there will be no appropriate program - however, this can be corrected with the "Browse" option where you should manually indicate the program location. Checking the "Always use the selected program ..." box will permanently associate the OOS file with the Apache OpenOffice program.

Step 3. Update Apache OpenOffice to the latest version

If, despite the association of the Apache OpenOffice program with the OpenOffice.org Spreadsheet file, the file still does not open, check the program version and possibly update it to the newest version. Some applications allow you to update from the program level, and for others you need to download the installer from the Apache Software Foundation page and install.

Step 4. Check for the following problems with the OOS file

If the above steps do not help, you can assume that the file itself is not correct. The most common file problems are:

The OOS file may be unusually small compared to the original file. This is most often caused by a problem while downloading the OOS file. Downloading the file again should fix the problem.
The most common cause here is computer viruses. A quick virus scan using an up-to-date antivirus program should clear up any doubts. Some antivirus vendors also provide free online scanners. The scan should cover the entire computer, not only the OOS file that we want to open. As a result of the scan, sometimes it is not possible to recover OOS files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
A typical compatibility error - the program does not support the older version of the OOS file. On their websites, developers usually offer free solutions to such problems, e.g. in the form of a conversion program or an older version of the program.
There can be many reasons for the failure. The repair method must be adapted to the type of file and damage. Sometimes the program itself has options to repair the most popular OOS file corruption. The easiest way to restore the file is from a backup or by contacting OpenOffice.org Project Team, but this one can be expensive. Not all damage can be reversed.
The program can also signal the fact of encryption. The encrypted file OOS except for the special designation, works normally, but only on the device where it was encrypted, before transferring it to another machine, decryption is required.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. The problem is only writing to the file, not reading it. Copying the OOS file to another location will fix the problem.
This problem only occurs with more complex files. You may find that another program you are using is preventing you from working with the file. Running programs (including those in the background) should be verified. Sometimes it is necessary to wait a while before referencing the OOS file again. Some anti-virus or backup software may occupy the OOS file for a certain period of time. If the problem persists, restart the machine.
