About Parquet Editor
A Comprehensive Online Parquet Tool
Parquet Editor is a tool built for developers, data scientists, and analysts who need to inspect or change Apache Parquet files without setting up Python, Spark, or any other local environment. Open a file, review its schema, add or delete rows, and download the result - or start from a blank schema and build a new file from scratch.
Because everything runs locally in your browser via WebAssembly, your files never touch a server. That makes it a practical choice when you just need a quick look at a dataset, or when the data itself is sensitive enough that uploading it isn't an option.
Privacy-First Design
Parquet Editor is built with privacy as a core principle. All file processing happens entirely within your browser using WebAssembly technology. This means your data never leaves your device - there are no server uploads, no data transmission, and no external storage. Your sensitive data remains completely private and secure on your local machine.
Powerful Browser-Based Processing
Parquet Editor brings enterprise-grade data processing capabilities directly to your browser. You can view, edit, create, and manipulate Apache Parquet files without installing any software or relying on external services. The tool supports complex data types, schema modifications, and efficient handling of large datasets.
