Data Validation & Schema Suite

Data Validation & Schema Suite — Keep data clean with one API: validate JSON, diff objects, convert YAML, turn CSV into JSON, and test and replace text with regular expressions.

🧮 Rules-based — NOT AI

🚀 Newcomer launch pricing — limited-time introductory rates while we earn our first reviews.

Built for data engineers, ETL and pipeline developers.

Why this exists

Data-pipeline validation means a pile of one-off scripts for schema checks, format conversion, and regex cleaning.

What you get

One API key validates, converts, and cleans data with deterministic rules — the pipeline validation layer.
