Hello Kinga,
Thank you for reaching out about the issue with your Excel file on OneDrive. I understand how concerning it is to lose version history especially when important updates are missing. It can be frustrating to see your file revert to an older state and feel like your recent work is gone.
OneDrive automatically keeps previous versions of files for a certain period but if the version history appears lost it may be due to sync issues or versioning settings. You can try restoring an earlier version by signing in to OneDrive online, locating the file, right-clicking it and selecting Version history. From there you can preview available versions and either restore or download the one you need. If you use the OneDrive sync app you can also right-click the file in File Explorer and choose Version history. Keep in mind that personal accounts typically store the last 25 versions while work or school accounts depend on library configuration.
Could you confirm if you are using a personal Microsoft account or a work or school account?
I hope this answer is helpful if you have further questions feel free to reply back
Regards,
Marcelo
