BROWSER-LOCAL AVRO VIEWER

Inspect Avro files without uploading them.

Open Avro object container files to inspect records, the embedded writer schema, blocks, and codecs. A dedicated browser worker performs decoding.

Avro object container format only. Single-object encoding and RPC messages are not accepted.

Schema beside data

Inspect the embedded writer schema, named types, logical-type annotations, and decoded records in one local workspace.

Bounded decoding

File, record, block, collection, value, and nesting limits constrain work. Sync markers and Snappy CRC-32 checksums are verified.

Your Avro file stays local

File contents are processed in browser memory. Ordinary page and asset requests still reach the hosting provider.
