Spanish Market Research Questionnaire Review

I'm seeking a native Spanish expert from Spain to review a market research questionnaire pertaining to an alcoholic beverage. Your task will be to check for grammar and spelling errors, as well as the cultural relevance of certain phrases. Additionally, you will need to ensure consistency in the usage of the T-form of the language.

The questionnaire is designed to take approximately 8 minutes to complete. You will receive it in an Excel file, and will simply need to add your comments in an adjacent column to highlight any errors and suggest appropriate corrections.

Key Areas of Focus:
- Product-related questions: These will require particular attention to ensure they are adequately phrased for our target demographic.
- Feedback and open-ended responses: These sections will also need careful scrutiny to ensure they are culturally relevant and grammatically correct.

How I would like you to flag corrections:
- Please highlight errors in the background color of the relevant cell.

Ideal Skills and Experience:
- Native Spanish speaker from Spain
- Experience with market research questionnaires
- Excellent understanding of grammar and spelling
- In-depth knowledge of Spanish cultural nuances
- Consistency in the usage of the T-form
- Proficiency in using Excel for review tasks
