How to open a .avro file (Windows, Mac, Linux)

Q: Why can't I open my .avro file?

Usually your computer lacks an app that understands Avro. Install one of the apps listed here, or convert the file to a more common format.

A .avro file is a Apache Avro. If double-clicking does nothing, your computer simply does not have an app that reads Avro yet. Here is how to fix that on each operating system, using free software wherever possible.

Open a .avro file step by step

Confirm the file really is a .avro. Drop it into the WhatFileType file identifier, which reads its signature without uploading anything.
On Windows, open it with Python (fastavro) or avro-tools (Java).
On Mac, use Python (fastavro) or avro-tools (Java).
On Linux, try Python (fastavro) or avro-tools (Java).
Still stuck? Convert the .avro to JSON, which opens more widely.

Frequently asked questions

Why can't I open my .avro file?

Almost always because no installed app understands Avro. Install one of the apps above, or convert the file to a format your existing software already reads.

How do I read an Avro file?

Use a library such as fastavro in Python or the avro-tools jar, both of which can print the embedded schema and dump the records to JSON.

What is the difference between Avro and Parquet?

Avro is row-based and self-describing, ideal for streaming and writing records one at a time. Parquet is columnar, ideal for analytical reads across many rows.
