Build 2.9.0.43 of xlsgen improves text boxes in XLS and XLSX files.

It applies to both floating text boxes and chart text boxes.

Text boxes now support formulas and formatting styles.

Supporting formulas means that the content of the text box can be governed by the content of another cell, in the same spreadsheet, or in another spreadsheet.

Supporting styles means that the content of the text box can be customized to support background color, a border and the alignment. Note that regarding the font formatting, it is already supported by using rich labels as opposed to regular labels.

For more information and a code sample, see the documentation page related to text boxes.
