I have written few details in MS word document & now i wanted to upload this file in one project in jira.
Please let me know can we upload Word, PDF, Excel in Jira?
@Gayatri Mali Welcome to the community.
You can attach document or for that matter any file to Jira issues but there is not specific place where you have upload documentation.
Here is a link on how to attach file to jira issue - https://support.atlassian.com/jira-core-cloud/docs/attach-files-and-screenshots-to-issues/
Now if you want better experience for documents, you can try Atlassian Confluence. Confluence seems more focused towards your use case.
