Long-time users of Office often need to copy Excel data into Word and vice versa. There are often errors, though, as Word likes to convert spreadsheets into tables that often do not fit the document’s formatting or size.
Instead of converting into a table, use the “Save as Picture” option. While this doesn’t allow for further editing, the image preserves all the original data and styles.
In Excel, select the data and copy (Ctrl+C).
In Word, right click and select “Save as Picture”.
That’s it!
