Question: I have an excel document of multiple separate sheets. 

I can import them one at a time by saving the individual sheets as CSV’s but is there away to bring the entire document into QGIS? 

The information is point geometries.

Answer: 
There is a [plugin: Spreadsheet Layers](https://plugins.qgis.org/plugins/SpreadsheetLayers/) that can load excel layers into QGIS. I did not test the plugin and never used it, but you can give it a try to see if it can solve your problem.

There are some limitation in the plugin, you can check everything from plugin page: [QGIS-SpreadSheetLayers](https://github.com/camptocamp/QGIS-SpreadSheetLayers)
This sounds like an issue around data arrangement. Without rearranging the data, in short the answer is no.
