If you attach a file, please be careful that it does not contain confidential data
(address, telephone, ID#s, etc.). This is a public forum, searchable through Google and other web search engines, most of which will also search inside the documents you attach here.
Work with a new copy of your document
Be careful if you use these methods to anonymize a document, that you save it to a new file and don't save the changes to your original document
. Use File > Save As, then give it a new name before you make any of these changes.
Anonymize your data
You can often remove confidential data while preserving the structure of a document by using OOo's Find and Replace feature. E.g. you can use
- Edit > Find & Replace
Search for: [a-z]
Replace with: x
Options: Match case: YES, Regular expressions: YES
Repeat the above using [A-Z]
to scramble the upper case letters, and [0-9]
to scramble numeric data.
Replacing the letters and numbers in a confidential letter like this:

This takes only a few seconds and preserves the essential structure of the document, including formatting, but makes it very difficult for anyone to discern personal details from it. Change the upper-case letters also if your text contains private information in all upper-case.
Remove personal information
If you upload a document, it may contain "metadata" that could reveal confidential information. This includes information shown under Tools > Options > OO.org > User Data.
If you have entered personal information there, you can prevent this information from being included when you save a document by setting the option Tools > Options > OO.org > Security > Options > Remove personal information on saving.
If you change any of the security options, make sure that you change them back to the appropriate settings
before you continue with your regular work.
Remove saved changes
A document may also reveal personal information through saved changes. If the document includes the saved changes, someone could take the 'x'ed-out document above and "undo" the changes to get back to the original.
Changes are saved only if Edit > Changes > Record is ON.
You can remove any saved change information using Edit > Changes > Accept or Reject > Accept All, then saving the document.
