Questionnaires, including the greeting, instructions for sections, questions, options for answers, scale labels etc. can be checked for spelling errors. There are several dictionaries available, including British English, American English, German with old or new spelling rules, and a few other languages.
1. Pick a dictionary.
At the very bottom of the questionnaire, you can pick a dictionary and start the spell check.
2. Check and correct misspelled words.
The spell checker puts every word that did not match with any dictionary entry into an editing field. Immediately after each editing field, alternatives are suggested. If one of them fits, just click on it to copy it into the text field. Otherwise, edit the text manually if necessary.
When all text fields contain correct text, click on the "Finish" button to save your changes.
