how to work with .xlsx files?
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

Writing a C compiler in 500 lines of Python
While I suspect I would learn more writing a tokenizer and parsing logic myself I find grammars much easier to read and maintain.
ANTLR is pretty good and is supported across several languages and something I had previously used for some quick Elasticsearch query syntax munging in Python. It also means you can often start from an already existing grammar.
The JS version of ANTLR didn't seem to work for me so for the SQL/JSONPath stuff ended up using the Moo lever and Nearly parser which was rather pleasant. https://nearley.js.org

Applicative Parsing
Parsers in nearley.js [1] are written in a very readable EBNF-like DSL; then they get desugared down to a JS file that's a lot like your snippet.
