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: 
After qgis3.8,you can direct access to sheets from XLSX/ODS files from browser,see the details: 

[Changelog for QGIS 3.8](https://www.qgis.org/en/site/forusers/visualchangelog38/index.html#feature-direct-access-to-sheets-from-xlsx-ods-files)
This sounds like an issue around data arrangement. Without rearranging the data, in short the answer is no.
