Additional settings-related features and issues within Microsoft Teams Free
Hi Charli, this is Marc. Thanks for reaching out to the community.
From what you’ve shared, I’d like to clarify a few details to better guide you. Are you trying to locate Excel files saved on your computer that were created or last modified in 2025, 2024, or 2023? Or are you referring to worksheets within a single Excel workbook that are labeled with those years? Another possibility is that you may have multiple workbooks and want to pull together all the sheets from different files into one place. Each scenario has a different solution, so confirming your exact case will help in providing the right steps.
In the meantime, files shared in a Teams channel can be found under the Files tab of that channel, and behind the scenes, they are saved in the connected SharePoint site for your team. If the files were shared in a private Teams chat instead of a channel, then they would be stored in your OneDrive for Business, which is linked to Teams.
Best regards,
