Yes, Confluence can index attachments and will find their content in searches. The following file types are supported:
- Microsoft Word (.doc, .docx, …)
- Text (incl. XML)
- Powerpoint (.ppt, .pptx, …)
- Excel (.xls, .xslx, …)
The topic is also dealt with in Atlassian Answers and in a Confluence documentation already.

To search the content of other attachment types, you will need to use an attachment content extractor plugin. For more information, take a look at the following:
- Existing extractor plugins which you can install on your Confluence site. See this search on Atlassian Marketplace.
- Guidelines on developing your own attachment content extractor plugin. See our developer documentation on extractor plugins.
