Posted 12 November 2020, 4:55 am ESTHello,
I'm using both SpreadJS and Documents for excel, Java edition. I create a workbook using SpreadJS, defining a custom format for some cells (bold 12px Arial). Then I store the excel in the database, and acces it using Documents for excel to fill the workbook with data. When I show the document again. the format of those cells had automatically changed.
