Writing Style information into Excel

I am trying to preserve the style information while I read and then write an excel File. Seems like the style information is read when I read the file, but unfortunately when I write the file its not preserved.

Thoughts on how I can read and write the style information?

            excelFile = XLSX.readFile(file.path, {
                cellStyles: true
            });

            // some processing here!

            XLSX.writeFile(excelFile, fileName, {
                cellStyles: true
            });

@sheetjs After a conversation with @elad (https://github.com/hubba/js-xlsx/commit/5e9bca78f2b0c54242cefc8a358f3151232941ab#commitcomment-8039333) I was informed that the styling information is only read, and not written back to excel.

We offer this in the Pro compendium. Since companies have paid for the features already, it would be unfair to them if we turned around and made it available as open source. We have a longer comment in a gist.

Where does this stand today as far as merging xlsx-style into this main project?
