Normalize data keys or document explicit naming requirement

[bstopp]

Expected Behaviour

When using the terms Name and Path for the column headers in the library.xlsx, the plugin renders correctly.

Actual Behaviour

Only the literal terms name and path for the column headers in the library.xlsx will allow the plugin to render.

If we don't want to normalize these, then the documentation should explicitly state that name and path must be all lowercase. Though I feel like we should normalize the data, rather than expect an explicit value.

Steps to Reproduce

Change the header in any configuration to Path.
