This resource is designed to help you provide your students with accessible Microsoft Excel workbooks. The table below provides recommendations and links to appropriate guidance materials. Please note that the points raised here encompass both the values and ethos of the Universal design for Learning and the requirements of Accessibility legislation (Public Sector Bodies (Websites and Mobile Applications) (No. 2) Accessibility Regulations 2018) relating to resources made available via websites, including the Blackboard VLE.
Microsoft provides a mechanism for checking the accessibility of documents in Excel and a full description of the method for running this check is provided at the end of the table below.
|What to think about||What to do|
|Complexity of data sets||Breakdown complex data sets into logical groupings
Use separate sheets for new data sets and tables
|Index page||For complex data sets with multiple sheets, use the first sheet for an index page.|
|Worksheet names||Use relevant and names for each sheet in a workbook and delete unused sheets.|
|Logical structure and path||Keyboard only users tend to follow a logical path, starting at A1 and work down to find a table.
Avoid locating data and tables in less obvious positions on the sheet.
|Save location||Save the workbook with the cursor focused on cell A1 to give a consistent starting point, unless you want to draw attention to a specific cell to start.|
|Filename||Save the excel workbook with an appropriate and descriptive title.|
|Tables||Keep the table as simple as possible.
Avoid using merged cells for data or headers
|Cell dimensions (height and width) and content||Adjust the cell dimensions to ensure that all text or data is visible within the cell.
Indicate empty cells in a table by including a zero, null or n/a, avoid leaving them blank.
|Images, diagrams, charts and graphics||Use ALT text to provide a clear description of any type of graphical object or image added.
Describe the content and purpose of the object.
· Try to do this in one or two short sentences.
· Avoid repeating content provided elsewhere on the page.
Decorative images do not need explanatory ALT text but it does need to indicate that the image is decorative.
A more detailed image description may be required in the body of the sheet where specific details and ideas are to be conveyed.
Avoid using visual characteristics alone to convey information.
Avoid including images of text.
Avoid using any content that flashes or flickers.
