 Let's walk through the code.  The Crossref path is in cell B2 and the DOI is added to cell B3.  The full path is
 created in the Google Sheet function 'CONCAT'.  Here is an example call to get the data.

 ## 3 Conclusion
 In this brief tutorial you can see how Google Sheets and the ImportJSON addon allows you to process any API data.
-Given this example, you can create spreadsheet views fo API data and even integrate data from multiple sources.
-The only thing to be aware of is that the more calls to APIs that you make in one sheet the slower the over all
+Given this example, you can create spreadsheet views of API data, and even integrate data from multiple sources.
+The only thing to be aware of is that the more calls to APIs that you make in one sheet, the slower the over all
 sheet will work, but this of course depends on your access speed, so you may need to optimize how you import the data.
