Rewrite Notebooks Programatically

Avinash_Narala

Hello,

I want to refactor the notebook programatically. So, written the code as follows:

 

import requests
import base64

# Databricks Workspace API URLs
workspace_url = f"{host}/api/2.0/workspace"
export_url = f"{workspace_url}/export"
import_url = f"{workspace_url}/import"

# Databricks personal access token
token = "***********************"

# Notebook path
notebook_path = "/Workspace/Users/Avinash/Old_Notebook"
new_notebook_path = "/Workspace/Users/Avinash/New_notebook"

# Function to export notebook content
def export_notebook():
    export_payload = {
        "path": notebook_path,
        "format": "SOURCE"
    }
    response = requests.get(export_url, headers=headers, json=export_payload)
    response.raise_for_status()
    return response.json()["content"]

# Function to refactor notebook content
def refactor_notebook(content😞
    # Example: Replace all occurrences of 'old_variable' with 'new_variable'
    new_content = content.replace("hive_metastore", "test_catalog_ph")
    return new_content

# Function to import modified notebook content
def import_notebook(new_content):
    import_payload = {
        "path": new_notebook_path,
        "content": new_content,
        # "overwrite": True
    }
    response = requests.post(import_url, headers=headers, json=import_payload)
    if response.status_code != 200:
        print(response.content)
    response.raise_for_status()
 
# Main script
if __name__ == "__main__":
    # Export notebook content
    notebook_content = export_notebook()
    decoded_content = base64.b64decode(notebook_content).decode('utf-8')

    # print(decoded_content)
    # Refactor notebook content
    new_notebook_content = refactor_notebook(decoded_content)

    encoded_content=(base64.b64encode(new_notebook_content.encode('utf-8')))

    #print(encoded_content)
    #print(base64.b64decode(encoded_content).decode('utf-8'))

    # Import modified content back to Databricks
    import_notebook(encoded_content)

    print("Notebook refactoring complete.")

 

 

I am able to rewrite the content by exporting the notebook as Json. But unable to import the notebook from the Json to my workspace and getting the error as:

HTTPError: 400 Client Error: Bad Request for url.

Can you please help me with this

Hello Kaniz,

I've implemented steps(1-4) as you instructed, but the issue I am facing is while importing my notebook.

In detaiI, I can export my notebook as json an can work with the json(replacing some specific words), but while uploading that json as notebook I am not able to do it.

I tried in two ways,

1.overwrite the existing notebook.

2.creating new notebook.

So, If you provide How can I create a notebook in my databricks workspace with the json content I have. It will be really helpful .

Thank you.
