How to change the worksheet background
Sometimes, when editing a worksheet we have created by uploading a file, we find an error or want to change something without modifying the fields we have already added.
We can do this with the Change page background option, that we can find on top of the current page.
We can replace the current page background by uploading a new image or PDF file. This will overwrite the existing one with the one uploaded. To avoid errors, only the current page will be modified if we upload a PDF with multiple pages.
