First, manually collect the data from LinkedIn pages. This involves copying and pasting the relevant data into a structured format such as a CSV or Excel file. Be sure to only collect publicly available information and comply with LinkedIn's terms of service and data privacy policies.

Organize the collected data into a consistent format. This typically involves cleaning up any inconsistencies in the data, such as missing values or incorrect data types. Use spreadsheet software like Microsoft Excel or Google Sheets to ensure the data is well-structured, with each column representing a field and each row representing a data entry.

Once the data is organized, export it to a CSV file format. This format is widely supported and easily processed by Databricks. Ensure the CSV file is saved with a clear and descriptive name to avoid confusion during the import process.

Log into your Databricks workspace and navigate to the Data tab. Use the "Add Data" option to upload your CSV file to the Databricks File System (DBFS). Follow the prompts to select your file from your local system and complete the upload process.

Open a new notebook in Databricks and use PySpark to create a table from your CSV file. This can be done by running a command like:
```python
df = spark.read.csv("/FileStore/tables/your_file_name.csv", header=True, inferSchema=True)
df.createOrReplaceTempView("linkedin_data")
```
This command reads the CSV into a DataFrame and creates a temporary SQL view for further processing.

Use Spark SQL or DataFrame operations to further clean and transform the data as required. This could involve filtering, aggregating, or joining data to meet your analysis needs. For example:
```python
clean_df = spark.sql("SELECT * FROM linkedin_data WHERE column_name IS NOT NULL")
clean_df.show()
```
This ensures that your data is ready for analysis or further processing.

Finally, write the cleaned DataFrame to the Databricks Lakehouse in a format like Delta Lake, which supports ACID transactions and scalable data processing. Use the command:
```python
clean_df.write.format("delta").mode("overwrite").save("/mnt/datalake/linkedin_data")
```
This saves the data in a robust format that is ready for advanced analytics and machine learning workloads.

By following these steps, you can manually move data from LinkedIn pages to the Databricks Lakehouse without the need for third-party connectors or integrations.
