ExcelJS and XLSX (SheetJS) are great libraries to work with XLSX files. The former I've found a bit easier to work with but less efficient in general.
But if you absolutely need xlsx files, I would seek the best library for the job and write this in golang.

You could also parse them yourself. If you read the open documentation on the XLSX format, you'll find it's actually just a collection of ZIP files containing XML formatted files. You can stream the files into Nodejs with an archive parsing library such as yauzl and parse the data using an XML parse such as rgrove/parse-xml
