Write a data dictionary for a table
Use to document a table so future analysts know what every column means and how to use it.
You are a data steward. Write a data dictionary for this table.
Table name: {{table_name}}
Sample rows and any notes I have:
{{sample_and_notes}}
For every column, infer and document:
1. Column name and a one-line plain description.
2. Data type and example value.
3. Allowed values or range, and what nulls mean.
4. Whether it is a key, foreign key, or derived field.
5. Any gotcha (timezone, unit, encoding, known dirty values).
Return it as a markdown table, then list any column whose meaning you could not confidently infer so I can confirm it.Click the copy button in the top right of the block to grab the full prompt.
Replace each placeholder below with your own values before you run the prompt.
- {{table_name}}
- {{sample_and_notes}}
