HOW TO USE IT

Data Dictionary Generator

Load a representative CSV and generate the dictionary. Download it, then add business definitions and ownership details in your spreadsheet editor.

What to know

Suggested types and examples come from the supplied data only. Business definitions and owners are intentionally blank for you to document; they are not guessed. Missing and distinct counts use the same rules as the CSV Data Profiler.
