Spell check in browser

We have a list of 850 standardised web pages in which there are a number of words joined together following an automated database update.
This task can be completed by:
1. Copy link from excel sheet into browser
2. Edit possible joined words in custom page editor
3. Update and save page. Ensure the pop-up confirms the save.
4. Repeat

Note that if you use the Chrome browser, the inbuilt spell check will automatically find those joined words when you click into the editor so there is no searching required. Unless you are confident, do not correct other words highlighted as incorrect by the spell-checker as it may be technical or British English. Due to the way in which the list of lessons were compiled, there may be pages in which there are no joined words at all.

Knowledge of science is not required.

At a rate of 5 per minute, this should take 3 hours; however do budget a little longer due to the monotony of the task and familiarisation.
