CSV reader recommendations...
The Sylvan.Data.Csv library is also the fastest CSV parser for .NET, and can load data about 3x faster than MTD based on my limited testing.

What's the best way to read an Excel file into a DataGrid in WinUi 3?
I don't want to disparage NPOI, because I'm sure it's great for its primary use-case, which is creating/editing spreadsheets. However, from a performance perspective it is one of the slowest libraries for reading Excel data in .NET. Since the OP seemed to be very concerned about performance and only needs to read data, this probably isn't the best choice.

Help needed with .xlsb files
I'm pretty sure NPOI doesn't support .xlsb. At least it didn't the last time I updated my benchmarks: https://github.com/MarkPflug/Benchmarks/blob/main/docs/ExcelBenchmarks.md

How would I use an Excel file as Data Source for SQLite connection?
If you're trying to load an Excel worksheet into a DataTable, I maintain a library that can make this quite easy: Sylvan.Data.Excel. It is available as a nuget package, open source, MIT licensed, and the fastest Excel reader for .NET.

Read .xls, .xlsx files using interop and import to datatable
It provides a forward only data reader (DbDataReader) for all common excel formats (.xlsx, .xlsb, and .xls). It is the fastest and lowest allocating Excel reader in the .NET ecosystem.

Microsoft .net XLSX to CSV library?
I maintain a couple libraries that should make this quite easy: Sylvan.Data.Csv, and Sylvan.Data.Excel. They are both open-source and MIT licensed. They are also both fastest-in-class at their particular tast.

Read Excel file in .NET 6 deployed on Linux?
It isn't exactly a full-featured library, but it is cross-platform and is the fastest and lowest allocating Excel reader that I'm aware of for .NET. That might not be a huge concern if you're just processing the occasional file.

The Fastest Csv Parser In Net
Thanks for this -- I've pushed a PR that corrects a slight incorrectness issue that biased the results in Cursively's favor, uses the original byte array directly instead of needlessly wrapping it in a MemoryStream, and uses the same optimization that you used to make SylvanSimplePool win in its category. CursivelyCsv is now the winner on my machine in this category when doPooling is on.
