## What it is
A .NET library that lets developers query Excel spreadsheets and CSV files using LINQ syntax, mapping worksheet rows to strongly-typed objects. It is explicitly unmaintained and the author recommends using newer alternatives.

## Use cases
- query excel spreadsheets with linq in c#
- read csv files into typed objects in .net
- filter spreadsheet rows like a database query
- map excel columns to class properties
- extract data from xlsx files in a dotnet app

## When to choose
- you are on legacy .NET code that already uses it
- you need simple LINQ-based querying of Excel/CSV and can accept an unmaintained dependency

## When to avoid
- starting a new project - the README says it is unmaintained and recommends alternatives
- you need modern Excel format support or active maintenance
- you cannot install the Microsoft Access Database Engine dependency

## Facets
- artifact type: library
- maturity: abandoned
- function: parser, data-science, etl
- domain: spreadsheets, files, developer-tools
- platform: dotnet, windows, cross-platform
- tags: excel, csv, linq, spreadsheet-querying, net-library
