Style format is broken after read and save the same file

template.xlsx

I attached my template I need to read and write some data using my file.

        var workbook = new Excel.Workbook();
        workbook.xlsx.readFile('./reports/templates/template.xlsx')
            .then(function(stream) {
                var options = {
                    useSharedStrings: true,
                    useStyles: true
                };

       stream.xlsx.writeFile("Test.xlsx", options)
            .then(function(){      
                console.log("Done.");
            })

    });

Please can you look, Thanks, David

Unfortunately, I cannot explore this (and many other issues) that I would like - I don’t have enough time for volunteer working as earlier.

If you would like to allow me to spend more time on open source activities around spreadsheet files (ExcelJS + XToolSet) or order me some issue being done, write me [e-mail].
