About parquet-viewer
parquet-viewer
Views Apache Parquet files as text (JSON or CSV).
Features
When opening a Parquet file, a textual presentation of the file will open automatically:
After closing the textual view, it is possible to reopen it by clicking on the link in the parquet view.
Backends
The extension supports different backends for parsing the files:
arrow
This is the default backend. This backend is a thin wrapper around the Apache Arrow C++ implementation and so should support latest and greatest parquet features.
parquet-wasm
This backend uses the parquet-wasm library which uses the "official" Rust implementations of Arrow and Parquet.
It support most compression algorithms besides LZ4, see https://kylebarron.dev/parquet-wasm/index.html#md:compression-support for details.
parquets
This backend uses the parquets TypeScript library, which is a fork of the unmaintained kbajalc/parquets library with some bug fixes.
It only supports parquet version 1.0.0 with snappy compression.
Format
The textual output can be either JSON or CSV based on the parquet-viewer.format setting.
A richer view
After getting the textual representation, it's possible to use other extensions like JSON Table Viewer (requires settings parquet-viewer.json.asArray) or Edit csv to get a richer view of the data (e.g. in a table).
Settings
The following setting options are available:
|name|default|description|
|parquet-viewer.backend|parquets|Which backend to use for reading the files| |parquet-viewer.format|json|textual output format| |parquet-viewer.logging.panel|false|Whether to write diagnostic logs to an output panel| |parquet-viewer.logging.folder|empty|Write diagnostic logs under the given directory| |parquet-viewer.logging.level|info|Diagnostic log level. Choose between: off, fatal, error, warn, info, debug or trace| |parquet-viewer.json.space|0|JSON indentation space, passed to JSON.stringify as is, see mdn for details| |parquet-viewer.json.asArray|false|Whether to format output JSON as one big array| |parquet-vierer.json.extension|json|File extension for the output JSON file| |parquet-viewer.csv.separator|', '|CSV separator|
Notes
Size limit
VSCode allows extensions to work on files smaller than 50MB. If the data is larger, it will be truncated a message indicating that will be appended to the output. See https://github.com/microsoft/vscode/issues/31078 for details.
