Hi and welcome to the forum!
Have you already closed the document from which you deleted the data? If not, try hitting Ctrl + Z to undo the changes.
Also, go to the location of the file on your computer. Go to Tools > Folder Options > View tab > select "Show hidden files and folders" and hit OK. Then look and see if a file with a similar name but with "~$" in front of it appears. If so, double-click that to open it and see if the data you deleted is there.
If that doesn't work, go to the Office Button > Excel Options > Save tab and look next to where it says "AutoRecover file location." Navigate to that location on your computer and see if there is a saved version of the file there.
