Parsing CSV?
I've been using CsvHelper for a long time and I quite like it. It's flexible and configurable enough to suit all my needs. Though the authors have unpleasant habit of introducing breaking changes (currently they are at major version 30).

Best language for manipulating an Excel file.
It's really slow compared to (for example) csvhelper. I tried to use the built in microsoft stuff to handle a data transformation routine using excel files, turning them into csvs and using the csv library sped up the process from 3-4 minutes to about 8 seconds.

BREAKING!! NPM package ‘ua-parser-js’ with more than 7M weekly download is compromised
https://www.nuget.org/packages/Newtonsoft.Json/ https://www.nuget.org/packages/AutoMapper/ https://www.nuget.org/packages/Dapper/ https://www.nuget.org/packages/FluentValidation/ https://www.nuget.org/packages/FluentAssertions/ https://www.nuget.org/packages/NUnit/ https://www.nuget.org/packages/xunit/ https://www.nuget.org/packages/YamlDotNet/ https://www.nuget.org/packages/Moq/ That is simply not true. Mature c# projects purposely maintain no downstream dependencies and is they do, it's to a major reputable lib. See for yourself - these are staple third party packages commonly used. Anything dependency starting with System or NETStandard is Microsoft maintained.
