The project with a single 11,000-line code file
In Pascal that is really common, since the files are the modules. You publish your library as one file, and the user can import it by the file name.
I ran wc on FreePascal to search for some. There are a few, but not as many as I expected.
9k file, data structures for the compiler itself: https://gitlab.com/freepascal.org/fpc/source/-/blob/main/./c...
30k file: Pascal parser/scope resolver: https://gitlab.com/freepascal.org/fpc/source/-/blob/main/pac...
And the record:
119k file, Sharepoint API (but it seems to be autogenerated): https://gitlab.com/freepascal.org/fpc/source/-/blob/main/pac...
As far as libraries go, this is one of my favorites:
23k file, regular expression library: https://github.com/BeRo1985/flre/blob/master/src/FLRE.pas
I searched my own files and found a 197k file to parse HTML entities. But that was an autogenerated trie (one switch/case for each letter)

how to work with .xlsx files?
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.

What kind of Programmer / language should I be looking for?
Sure. I manipulate excel files programatically in the browser all the time. I don't really understand your exact workflow, but I use Javascript with xlsx and React.

React App Won't Read xlsx File
Looking at the xlsx documentation, to parse files in the browser, rather than readFile, you use read, which is designed to parse binary data directly, rather than read from disk. There are a bunch of different formats if you go to the XLSX NPM page and scroll down to "Acquiring and Extracting Data". Importantly, it seems the data must already be serialized, so a Blob won't work, but we can work with that.

We compete with GitHub. Bing does not show our website
Last year, Bing and Edge erroneously flagged our website https://sheetjs.com/ as "dangerous": https://i.imgur.com/BvA3zrk.png
At the time, there was no "Safety Report" to indicate why Bing thought it was dangerous. The report page linked to https://www.bing.com/toolbox/bing-site-safety?url=https%3a%2... and it said "That web page doesn't exist"
To fix it, we had to register with "Bing Webmaster Tools" (https://www.bing.com/webmasters/about) and raise a support ticket.
Within a few days, the issue "resolved itself". It's possible that raising a ticket forced some automatic refresh of the indexed data for the domain.
