Worksheet is invalid (Excel only)

If the worksheet is empty or the only text in the document is in shapes, Accessibility Assistant will mark the specific worksheet as invalid. Opposite Word and Powerpoint, Excel cannot export worksheets with no content detected.

To make the worksheet valid there has to be written text in the document. Text written in shapes will need to be moved out of the shapes and put into the worksheet itself. When the worksheet contains all the text, clicking "Solve" will reevaluate the document, and it will turn green if the worksheet is valid.
