    What's new

    Product updates for viewparquet — the private, in-browser Parquet workbench.

    2.0Changelog

    A new workbench for Parquet: multi-tab SQL and a virtualized results grid — all running locally in your browser with DuckDB-WASM. AI assistant coming soon.

    SQL editor

    Write full DuckDB SQL with tabbed queries, schema-aware editing, and one-click run. Export results to Parquet, CSV, or JSON without leaving the tab.

    Results grid

    • Virtualized Glide grid for smooth scrolling on large result sets
    • Type-aware cell coloring for numbers, dates, IDs, and nulls
    • Per-column stats: cardinality, ranges, and null rates

    AI assistant (coming soon)

    • Ask questions in plain language and get SQL grounded in your open file
    • Run generated SQL or insert it into the editor in one click
    • Chat tabs so you can keep multiple threads while exploring

    Privacy-first

    Files never upload to a server. Processing stays in-browser — open DevTools Network and confirm zero uploads.

    1.2Changelog

    Faster loads, saved files, and a cleaner viewer shell for day-to-day Parquet inspection.

    Viewer

    • Remember recently opened files in IndexedDB for quick reopen
    • Improved Parquet and GeoParquet detection and error messages
    • Dark mode aligned with the rest of the app
    1.1Changelog

    Broader format support and export paths for validated datasets leaving the viewer.

    Formats & export

    • GeoParquet viewing alongside standard Parquet
    • Export query results to CSV and JSON
    • Clearer schema and column type display in the grid
    1.0Changelog

    Initial release — open Parquet files in the browser and explore them without installing anything.

    Core

    • Client-side Parquet viewing powered by DuckDB-WASM
    • No accounts, no uploads, no server-side data processing
    • Support for .parquet and .geoparquet files
