What they did
The person, who works in automation at a large organization, handed Claude a massive CSV dump of data. They asked it to shape that file into something more useful for spotting changes over time.
How it went
Claude produced a working dashboard that showed trends over time. The comment did not include numbers, and it did not explain how much checking or cleanup was needed.
Tips
Ask the agent to call out any suspicious rows, missing fields, or assumptions before you rely on the output. If you want a dashboard you can reuse, specify the format and the metrics you need up front.

Try it yourself with Claude

I’m uploading a large CSV export from [system/process]. First, inspect the data and tell me what columns, time range, and obvious quality issues you find. Then build a single-file dashboard that shows trends over time for [metric 1], [metric 2], and [metric 3], with filters for [team/category/date range]. Pause and ask for my approval before you save, export, or overwrite anything. After that, list the assumptions you made and anything I should verify manually.
