Notepad++ plugin for CSV validation, formatting, and data cleaning

Pluginfree

CSV Lint is a free Notepad++ plugin for inspecting and cleaning CSV and fixed-width data files. It detects columns and datatypes, validates data against a schema, and converts between delimiters or into SQL, XML, or JSON — all processed offline with no cloud service. It's aimed at anyone doing manual data cleaning or quality checks before loading a dataset elsewhere.
