Why Use ChatDB Parquet Viewer?
In contrast to heavy-duty analytical tools like Row Zero or big data platforms, the ChatDB Parquet Viewer focuses on rapid, privacy-centric schema inspection. This tool is indispensable for developers debugging the output of distributed ETL (Extract, Transform, Load) pipelines.
All parsing happens in your browser via WebAssembly/Pure JS. No data is ever uploaded to a server.
Immediate feedback on compression codecs (Snappy, Gzip, Zstd) and column types, even for files up to 500 MB.
Designed for debugging structural integrity without the overhead of a full SQL database.
Frequently Asked Questions (FAQ)
Is it safe to upload sensitive data?
Yes! Actually, you aren't "uploading" at all. Since we utilize a "No-Backend" architecture, the file is read directly from your local machine into browser memory (ArrayBuffer) and parsed client-side. No data is ever transmitted over the network.
What file size can this viewer handle?
We recommend files up to approximately 500 MB. Larger files can be handled depending on your browser's available memory, as the tool loads the metadata and schema into an ArrayBuffer for local processing.
Which compression codecs are supported?
Our viewer provides immediate feedback on all major Parquet compression codecs, including Snappy, Gzip, Zstd, and LZO. You can see the codec used for each column under the "Row Groups" tab.
Does this tool require a back-end server?
No. This is a 100% browser-native tool. It uses the standard HTML5 File API and local parsing libraries (hyparquet) to ensure maximum privacy and zero latency from server roundtrips.
