- Ignoring missing keys that become empty cells
- Letting Excel reinterpret IDs and dates
- Mixing arrays of different shapes in one file
A 10-Minute Practice Routine
- Two minutes: write the brief for a real task on your list.
- Three minutes: generate and read the result end to end.
- Four minutes: edit - real details in, generic lines out, opening rewritten.
- One minute: save the prompt and note one thing to change next time.
How to Know You Are Improving
Track edit time per result for two weeks. When it drops, your briefs are getting better. When it spikes, the cause is almost always a vague input - go back to the tip about writing the goal in one sentence.
Frequently Asked Questions
Does it handle nested JSON?
Flat objects convert perfectly. Deeply nested structures are flattened as best they can be, or better converted level by level.
What if some objects have different keys?
The union of all keys becomes the header; missing values are written as empty cells.
Can I open the output in Excel?
Yes - open it as CSV or paste it into a sheet. Format ID and date columns as text to avoid surprises.
Is my data stored?
No, conversion happens entirely in your browser.
