Ask HN: What Are You Working On? (June 2025)

I'm building https://zenquery.app — a tool for querying large CSV, JSON, Parquet and Excel files using plain English. No SQL or coding required.

As a data engineer, I regularly have to dig through massive files to debug issues or validate assumptions — things like missing column values, abnormally large timestamps, inconsistent types, or duplicate records. It’s tedious and time-consuming, and that’s what led me to build this.

ZenQuery makes it quick and easy to explore data locally, without needing to spin up notebooks, write scripts, or upload anything to the cloud. It’s also useful for doing lightweight analytical QA if you're working with business data.

Happy to answer any questions.

Looks pretty cool. You should add a pricing section though. I thought the only cost one would have with this would be the LLM api costs.

Hey, thanks for checking it out. I have put pricing above the Download section, but I guess I could do better to make it more visible.

Will update.. thanks again..

Also, for marketing teams would be helpful to have a subscription based team bundle plan instead of a one time purchase per device! For example on my company I know that our marketing team would benefit a lot from using a tool like this. Anyways, great tool. Good job
