Sylvan.Data.Excel VS Sylvan

I'm a fan of Sylvan.Data.Excel myself

Here is a simple, complete gist showing how to turn a DbDataReader into an HTML table. The WriteHtmlTable extension method can be used with any ADO.NET compatible driver, which the Sylvan.Data.Excel and Sylvan.Data.Csv libraries both support.

I maintain a couple libraries that can help with reading the data files: Sylvan.Data.Csv and Sylvan.Data.Excel. I see no reason to not allow users to provide whichever format is convenient for them.

You can give my library a try: Sylvan.Data.Excel. You seem to be concerned about performance, so you can be happy to know it is the fastest Excel reader in the .NET ecosystem, by quite a wide margin. It is open source, MIT licensed, and is easy to use (in my biased opinion).

The easiest? I'm gonna have to disagree with you on that one. I believe my library, Sylvan.Data.Excel make it even easier (possibly the easiest) to read Excel data in .NET.

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.

I maintain a library, Sylvan.Data.Excel that might work for you. I claim it is the fastest Excel library in the .NET ecosystem. It is open source and MIT licensed, so feel free to use it however you wish. It has no external dependencies other than .NET itself.

I would recommend taking a look at [Sylvan.Data.Excel](https://github.com/MarkPflug/Sylvan.Data.Excel) if all you are trying to do is read data out of excel. It is a library that I maintain, and is extremely fast and easy to use.

I maintain a library that you can try: Sylvan.Data.Excel.

Here is a some sample code of how to echo the contents of an Excel spreadsheet as CSV to the client browser using my libraries Sylvan.Data.Excel and Sylvan.Data.Csv:

A while back I needed to process CSV with millions of records in a timescale of seconds. Sylvan Data was the best fit in terms of speed and memory efficiency. It might help you. https://github.com/MarkPflug/Sylvan

I maintain a couple libraries that aim to provide similar functionality to MTD: Sylvan.Data and Sylvan.Data.Csv.

I maintain a CSV library, Sylvan.Data.Csv, that shouldn't have any issue parsing this. You'll need to explicitly specify that space (' ') is the delimiter.

Here is a some sample code of how to echo the contents of an Excel spreadsheet as CSV to the client browser using my libraries Sylvan.Data.Excel and Sylvan.Data.Csv:

``` For reference, my implementation is here.

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.

Personally, I'd recommend Sylvan.Data.Csv, but being the author I'm probably a bit biased. Here is some CSV performance analysis that Joel Verhagen did for .NET libraries recently.
