I built ZenQuery(https://zenquery.app), a Mac desktop app that lets you explore your data files — like CSV, Excel, JSON, and Parquet — by simply asking questions in plain English.

Super low cost: ~$1 for 4,500+ questions

No setup, no coding. Just drop in your files and ask things like:

- “What’s the average revenue by region this year?”

- “Show the top 10 products by sales volume.”

One-time payment of $20 for lifetime access

Would love feedback from HN! Let me know what you think or how you'd use it.
