Hi @Govea, Hugo ,
Unfortunately, it is not possible to Sync Outlook Calendar into Excel Spreadsheet from Outlook itself.
If you’re looking for a more automated solution, you might consider using Power Automate to create workflows to connect SharePoint lists and Exchange calendars for automation.
Please refer to the workflow in this post to see if it meets your needs.
Solved: Sync outlook calendar with SharePoint List - Power Platform Community (microsoft.com)
Besides, please kindly understand that the Outlook tag here we mainly focus on general issues about Outlook desktop client. If you need more help with using code or development languages, it is recommended that you publish a new post with the “office development” tag so that you can get more professional help.
