Limitations

Large CSV/TSV data files streaming and display is very alpha and has the following limitations for now:

• Large datasets are paged and loaded into view for display with default page size set to 100K rows per page
• Columns sort only works for the paged data loaded and displayed in Table View 🀄 and doesn't sort data for the whole dataset
• Save data is also limited to max 100k rows for the currently displayed tabular data in Table View 🀄

Installation

Install Tabular Data Viewer 中 from VSCode Extensions tab (ctrl+shift+x) by searching for tabular data in Extensions: Marketplace sidebar view, or install it directly from VS Code Marketplace Tabular Data Viewer 中 extension page in a browser.

Deployments

Tabular Data Viewer 中 is designed to work with VSCode Desktop IDE version and also works with GitHub Codespaces in a browser:

Tabular Data Viewer 中 works in VSCodium too. However, VSCodium and other vscode extension compatible IDE flavors are not officially supported as they require additional testing in those IDE variants.

You can use tabular-data-viewer-x.y.z.vsix extension packages attached in Assets section with every published release of this extension on github. Follow install from .vsix instructions in your vscode extensions compatible IDE or online container service to install it.

If you prefer to use other IDEs that support VSCode extensions published in .vsix format and download your extensions from open-vsx.org, we recommend you try older Data Preview version of this extension.

Currently, there are no plans to publish this extension to Open VSX Registry due to poor publishing experience in that vscode extensions marketplace and low usage by majority of developers.

You can access custom Tabular Data Commands from View -> Command Palette... menu (ctrl+shift+p) by typing Tabular in the command search box:

All Tabular Data Commands start with Tabular Data: prefix, and exposed public Tabular Data Viewer 中 command Ids use tabular.data. prefix to enable other extensions to use Table View 🀄 and tabular data list commands.

Some of the Tabular Data Commands like View Table and List Data Resources are enabled in vscode file explorer and in code editors for the supported data file types and formats via the corresponding context menues in vscode IDE.

Currently supported Tabular Data 中 Commands include:

Tabular Data Viewer 中 v1.8.0 and above provides a custom Uri Handler for launching Table Views 🀄 and other tabular.data commands from a Url in a browser. All of the listed commands above can be launched from a browser using the following vscode:// Url format:

vscode://RandomFractalsInc.tabular-data-viewer/<command>[#<dataUrl>|?dataUrl=<dataUrl>]

which instructs a browser to open VSCode IDE Desktop application, activate Tabular Data Viewer 中 extension, and execute one of the tabular.data. commands via system-wide Urls. Commands that require a data file or data package Url accept that parameter via fragment/anchor (#) portion of the Url, or via dataUrl query parameter.

For example, the following vscode:// Url will display Table View 🀄 for the public https://github.com/datasets/world-cities data repository. Copy and paste this Url in your browser to try it:

vscode://RandomFractalsInc.tabular-data-viewer/viewTable#https://raw.githubusercontent.com/datasets/world-cities/master/data/world-cities.csv
