Plugin for Notepad++ that treats CSV files as (read only) SQL tables

CSV Query - Notepad++ plugin

A plugin to Notepad++ to parse different types of CSV files and display them in a table. The data is stored in a in-memory SQLite database (or MSSQL if configured), so you can write SQL queries against the data.

It tries to auto-detect separators, headers and column types. If it fails it asks you for it.

Planned features

• Support for more types of CSV files (more test cases, basically)
• Optimizations

Auto-detection

CSV Query detects the separator by calculating the variance in occurrence of characters on each line, then chose the one that seems best, preferring one of comma, semicolon, pipe or tab. It's certainly not perfect, but it handles all the files I regularly work with, which is why I wrote the plugin in the first place.

If the first line is "significantly different" from the rest it assumes the first line is a header and use it for the column names in the database.

CSharpSQLite

SQLite database rewritten in C#. I basically copied the whole codebase into CSV Query to get a single DLL (and to mess around with it a bit).
