# Data Import and Processing Errors

**Issue: When trying to create a project, the application redirects to the Settings page.**

- **Solution**: This is expected behavior on the first use. The application's AI features require a personal Google API key. You must follow the instructions to obtain a key from the Google Cloud Console, ensure the **"Generative Language API"** is enabled for your project, and then paste the key into the settings field and save it.

**Issue: My CSV file upload fails or the data does not appear correctly.**

- **Solution**: Check your data file format very carefully. The application requires a **CSV file** with exactly two columns, and the headers must be spelled precisely as `ErrorText` and `CorrectedText`. Using different names, having extra columns, or saving the file in another format (like `.xlsx`) will cause import errors.

**Issue: The data processing step seems stuck or is taking a very long time.**

- **Solution**: This step involves creating a detailed "linguistic blueprint" for each text pair, which can be time-consuming for large datasets. It is crucial that you **do not close the browser tab or navigate to another page** while processing is in progress, as this will interrupt it.
