Start by exporting your survey data from SurveySparrow. Log into your SurveySparrow account, navigate to the specific survey you wish to export, and look for the export option. Typically, you can export data as a CSV or Excel file. Download the data to your local machine for further processing.

Before importing the data into Snowflake, ensure it is clean and formatted correctly. Open the CSV or Excel file and check for any inconsistent data, missing values, or formatting issues. Make necessary adjustments to ensure the data is consistent and ready for upload. Save the final version of the file in CSV format as it is widely supported for data import operations.

Log into your Snowflake account and create a new database and table to store the survey data. Use the Snowflake web interface or SQL commands to create a database and define the table schema that matches the structure of your CSV data. For example:
```sql
CREATE DATABASE SurveyData;
USE DATABASE SurveyData;
CREATE TABLE SurveyResponses (
ResponseID STRING,
Question1 STRING,
Question2 STRING,
...
);
```

Use Snowflake’s web interface or SnowSQL (Snowflake’s command-line tool) to upload your CSV file to a Snowflake stage. If using SnowSQL, you can run the following command:
```shell
snowsql -q "PUT file:///path/to/your/file.csv @%SurveyResponses"
```
This command uploads the CSV file to the stage associated with the `SurveyResponses` table.

With the CSV file uploaded to the stage, you can now load the data into the Snowflake table. Execute a `COPY INTO` command to transfer data from the stage to your table:
```sql
COPY INTO SurveyResponses
FROM @%SurveyResponses/file.csv
FILE_FORMAT = (TYPE = 'CSV' FIELD_OPTIONALLY_ENCLOSED_BY = '"');
```
This command assumes you have defined a suitable file format for CSVs.

After loading the data, it is crucial to verify that the import was successful. Use SQL queries to check the contents of the `SurveyResponses` table:
```sql
SELECT * FROM SurveyResponses LIMIT 10;
```
Review the output to ensure that the data appears correctly and that all expected records have been imported.

To streamline future data transfers, consider creating a script or using Snowflake's Task feature to automate the process. You can schedule regular exports from SurveySparrow, and set up scripts to automate the import process using SnowSQL or Snowflake's Task scheduling, ensuring data is consistently updated.

By following these steps, you can move data from SurveySparrow to Snowflake Data Cloud without using third-party connectors or integrations.
