Analysis Tools and CMS Public Data Formats

Visualization and analysis tools are also available and we provide the data in several open, easy-to-use formats.

Click here to view the data in your browser.

The data is available in several formats:

• .ig files, which are zipped json files used for the iSpy event display
• .csv (comma-separated-value) summary files
• .json (JavaScript object notation) summary files
• .root files (for certain datasets)

For the more advanced user, several APIs are available:

• C++
• python
• ruby (on its way)

A special thanks to I2U2 for development of the browser-based event display
