Hi,

I'm trying to convert the sheet of an excel file to csv by calling this method
XLSX.writeFile(workBookFinal, "./temp/tempCsv.csv", {bookType: "csv"});
everything works fine. However, I noticed that if a cell contains the string ID as text, quotes are inserted inside the csv.
For example if I have a row with 3 cells valued like this

i will get:
A,B,"ID"
I expect:
A, B,ID

Thanks

Excel treats files that start with ID as "Symbolic Link": https://web.archive.org/web/20140929030911/http://support2.microsoft.com/kb/323626

The parser enforces the same logic.

To ensure that there is no confusion, the writer always wraps every ID in double quotes. The quotes are not needed in any other place.

To immediately fix this issue (only quote the first column), https://git.sheetjs.com/sheetjs/sheetjs/src/branch/master/bits/90_utils.js#L115 should be changed to

if(txt == "ID" && row.length == 0) txt = '"ID"';
