Dear Alcris Jacob,
Good day! Thank you for posting your query in our community.
Based on your description, query connection not present in the "Queries & Connections" in Excel. To not delay your work, you can check whether you can see the Query tab when clicking a cell in the query, and then click Edit, like the below image:
To check whether the problem is related to a specific file or the Excel application, could you please try to create a new simple file to see the result?
If the problem doesn't happen on a new file, then the problem might be related to this specific file. Then you can try to copy the content to the new one.
If the problem also happens on a new file, the problem might be related to the app. Here are some suggestions, and I hope they can help you:
- You can try Office safe mode to determine if the third party add-ins affect the office program.
- Try to fix Office client, by performing a repair. Try a quick repair first, and if that doesn't work, try the online repair.
If the problem persists, please provide some information for me:
- A screenshot of your Office Product Information(open Excel>File>Account>capture a screenshot of the Product Information column)
- Does the problem happen on all the Excel files? Or this specific file?
Sincerely,
