I am no stranger to Excel and tech in general, however this stumped me! This all occurred on the corporate laptop where we connect to the network remotely using a security token ID. Any help is extremely appreciated as I would hate to have to do hours of re-work.

I was working in an Excel spreadsheet, when suddenly the Excel application started glitching. Specifically, any updates to a given cell would not immediately reflect. The application would just freeze up awkwardly, and I could only view the change after toggling to a different tab and returning to the tab with the updated cell. Instead of clicking the Save button, I clicked the Exit button on the Excel file as I know a pop-up is to be triggered if changes have been made since the most recent save. The file closed with no prompts popping up, so I figured that was because I had recently saved the file which I distinctly remember doing. I then rebooted the laptop, logged in again with new token as we typically do each time, expecting to see all my updates when re-opening the file. Especially because the time stamp of the file clearly indicated the point in time right before the reboot. But the file completely reverted to the original state! I even checked many other local folders including Downloads, Documents, Desktop. I checked the Recent Files panel within the Excel file but all versions were also in the original state. I looked for the Auto-recovery panel but none was available.

I am panicking because I am really in a bind and time crunch at this time of the year. I considered consulting our IT team but they are usually very slow and their help would most likely be too late, if they can even recover the updated file. Is it even possible to recover the updated file in general now? What was the problem in this series of events, and what would have been the best solution? Any other advice or insight to help me out? Thank you all!
