Start by exporting data from WorkRamp. Log into your WorkRamp account and navigate to the specific module or report containing the data you need. Use the built-in export functionality to download the data in a CSV or Excel format. Ensure you have the necessary permissions to access and export the data.

Once you have the exported file, open it to clean and format the data as necessary. Ensure that the data aligns with Snowflake's acceptable formats and data types. Remove any unnecessary columns and reformat date fields or number formats to match Snowflake standards.

Log into your Snowflake account and ensure your warehouse is running. Create a database and schema where you intend to load the WorkRamp data. Use the Snowflake UI or SQL commands to create these structures. Example:
```sql
CREATE DATABASE workramp_data;
CREATE SCHEMA workramp_data.public;
```

Define a table in Snowflake that mirrors the structure of your prepared data. Use the Snowflake UI or a SQL command to create this table. Ensure that your data types in Snowflake match those in your CSV or Excel file. Example:
```sql
CREATE TABLE workramp_data.public.workramp_export (
id INT,
name STRING,
completion_date DATE,
score FLOAT
);
```

Use the Snowflake web interface or SnowSQL command-line tool to upload your CSV or Excel file to a Snowflake internal stage. For the command line, use:
```bash
snowsql -a -u -f
```
Alternatively, use the Snowflake UI to upload the data file directly to the stage.

Execute a COPY INTO command in Snowflake to load the data from the stage into the table you created. This command should specify file format options that match your data file (e.g., field delimiter, header row). Example:
```sql
COPY INTO workramp_data.public.workramp_export
FROM @workramp_data_stage/workramp_export.csv
FILE_FORMAT = (TYPE = 'CSV' FIELD_OPTIONALLY_ENCLOSED_BY = '"' SKIP_HEADER = 1);
```

After loading the data, verify its integrity by running a few SELECT queries to ensure that the data has been accurately imported. Check for discrepancies such as row counts, data types, or content issues. Example:
```sql
SELECT COUNT(*) FROM workramp_data.public.workramp_export;
SELECT * FROM workramp_data.public.workramp_export LIMIT 10;
```

By following these steps, you can effectively move data from WorkRamp to Snowflake without relying on third-party connectors, ensuring data integrity and compatibility along the way.
