JSON Schema Validator
JSON Schema Validator is built for data engineers who need to validate and format pipeline configs, warehouse DDL, and serialized records before they hit production systems on a daily basis. Unlike online utilities that upload your production samples to a third-party server, DataEngUtils runs entirely in your browser: the file is read locally and never leaves your device. It is part of the Pro Parquet and Avro workbench — one of 35 data-engineering tools that read files locally and never upload them. Whether you are debugging a failed dbt run, preparing a handoff for analytics, or validating a file before it lands in Snowflake or BigQuery, JSON Schema Validator keeps your data on your machine.
Open it in the app
JSON Schema Validator runs in the DataEngUtils browser app on a Rust engine (Apache Arrow) compiled to WebAssembly — part of the Pro workbench, entirely client-side, and nothing is uploaded.
How it works
1. Open the tool
Open JSON Schema Validator in the DataEngUtils browser app — no install and no account required.
2. Paste or drop your input
Add the text, config, or file JSON Schema Validator expects. It is read locally in your browser and never uploaded.
3. Review and export
Inspect the result, copy it to your clipboard, or download the output directly from your browser.
Why not use an online tool?
Online format validate tools require uploading your serialized configs to a third-party server. For production work, that is a security and compliance risk. DataEngUtils runs a client-side engine in your browser — same convenience, none of the exposure.
