The built in spell check is likely going to be more effective overall (even on the 120 views).
That said, the workset and view aren’t needed for this process.
-
Use Dynamo to get the selected views, gather all text elements in the view, get the GUID of each text element and the text value as paired 2d list, and export the pairs to CSV.
-
In your editor of choice, run spell check on the second column of the CSV, overwriting the previous value(s).
-
In a new Dynamo file, read in the CSV data, transpose and split into individual lists so you have a list of GUIDs and a matching list of desired text note values. Take the first list to select the text notes (wherever they may be), and then use the second list to set the text note value.
