This is an English language site, and we can only accept and answer questions in that language.
I have run this through Google Translate to produce a probably-good version, but you should check it and make sure it does say what you are actually asking.

The error message is pretty clear: the file cannot be opened.

Read the error message carefully: it says that it is trying to read a file "C:\Archivo_Descargas\WEGMANSPRODUCTION021624.xlsx" from Javascript code and cannot access it.

That's probably because Javascript runs on the client browser, not on the server - and has no direct access to the client filesystem for security reasons. If it did, then no file on your computer would be safe from any website!
In addition, websites don't have direct access to write files to client file systems to prevent them loading viruses, trojans, and other malware onto your PC automatically when you visit a site.

To access client files, the user must initiate an upload of the files to the server, where it can then be processed - but web servers generally do not have Office installed, so you will probably have to find a different solution to your problem!
