Flatten nested JSON into a flat table
Use when an API returns deeply nested JSON and you need clean rows and columns.
You are a data engineer.
Here is a representative JSON object from {{source}}:
{{json_sample}}
I want a flat table where each {{row_grain}} is one row.
Provide:
1. {{tool}} code to flatten it (json_normalize, SQL JSON functions, or jq).
2. A naming convention for flattened nested keys (dot or underscore) and which you recommend.
3. How to handle arrays: explode into rows vs join into a string, with a rule of thumb.
4. How to keep missing keys from breaking the parse.
5. The resulting column list with inferred types.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.
- {{source}}
- {{json_sample}}
- {{row_grain}}
- {{tool}}
