Blackboard Bulk Grade Center Export

WHAT IT DOES

This productivity tool revolutionizes Blackboard Grade Center management by enabling bulk grade data export with complete customization. It scans your current Blackboard Grade Center page, extracting all visible student data including names, usernames, email addresses, student IDs, and all assignment/grade columns. You can then filter students by name or average grade range, select individual students or use the select-all-filtered feature, and export grades to CSV format with full control over which fields and columns to include. The script generates a formatted CSV that includes your chosen student fields (name, username, email, student ID) plus selected assignment columns, with your preferred delimiter (comma, semicolon, or tab). The export is automatically copied to your clipboard and also offered as a downloadable file with a timestamped filename. Column selection is persistent, allowing you to export only the grade columns you need.

WHERE IT RUNS

This script operates on Blackboard Grade Center pages at *://*.blackboard.com/webapps/gradebook/, *://*.blackboard.com/webapps/grade-center/, and *://*.blackboard.com/ultra/courses//gradebook. It integrates as a floating panel on the left side of your browser window when you navigate to any Blackboard Grade Center. The tool works with Blackboard's dynamic interface, detecting students and grade columns regardless of how they're rendered on the page and adapting to Blackboard's frequent UI changes, including both Original and Ultra course views.

HOW TO USE

Navigate to your Blackboard Grade Center page (any of the supported URLs).

The panel appears automatically on the left side of the screen.

Click "Refresh" to load all visible students and grade data from the current page.

Use the filter input to search students by name or username.

Use the average grade range inputs (Min/Max) to filter students by overall performance.

Check the boxes next to students you want to export, or use "Select All Filtered".

Select your preferred delimiter: Comma, Semicolon, or Tab.

Toggle which student fields to include: Name, Username, Email, Student ID, Timestamp.

In the "Columns" section, check/uncheck specific assignment columns to include in the export.

Click "Export Selected to CSV" to generate and download the CSV file.

The file is automatically copied to your clipboard and downloaded with a descriptive filename.

DOM PARSING AND GRADE DATA EXTRACTION MECHANISM

The tool succeeds by intelligently parsing Blackboard's Grade Center table structures across multiple interface versions (Original and Ultra). It uses multiple selector fallbacks including data attributes, class-based selectors, and structural table navigation to extract student information and grade data. The script identifies column headers and dynamically maps grade values to their corresponding assignments, building a structured data model that preserves the relationship between students and their grades. The grade filtering system calculates average scores from all visible assignment columns, enabling powerful grade-range filtering. Column selection uses a whitelist stored via GM_setValue, so the script remembers which assignment columns you want to export, automatically ignoring unselected columns in future exports. The export mechanism uses the Blob API to create downloadable CSV files and GM_setClipboard for clipboard integration, ensuring the data is available in multiple formats with proper CSV escaping for fields containing delimiters or quotes.

THE PANEL

The floating panel is draggable to any position on screen and remembers its location between sessions using GM_setValue. It automatically collapses to a small icon when minimized and expands on hover or click. The panel is resizable to suit your workspace needs and can be dismissed with the Escape key. It snaps to the left edge by default but can be positioned anywhere, with position persisted across browsing sessions for consistent placement. All settings persist automatically across sessions, including your delimiter preference, selected student fields, and column whitelist.

PLEASE NOTE

This script requires the free BotGentz extension to run user scripts on Blackboard. Blackboard frequently updates its Grade Center interface, which may temporarily break functionality; updates are released regularly to maintain compatibility. The script only reads visible grade data from the page and does not store or transmit any data externally. All processing occurs locally in your browser. Exported data includes only the fields and columns you select; verify your export settings before exporting to ensure you capture the necessary data. The script respects Blackboard's data visibility rules—only grade columns visible on the current page are available for export. For courses with many columns, use the column filter to quickly find and select specific assignments. Grade calculations for filtering use the average of all visible numerical grade columns; non-numeric values are ignored in the average calculation.
