Getting random characters after notebook metadata modification using Rest API
Hi chetanhiwale ,
Thank you for your feedback. We attempted using the example you mentioned: print ("microsoft \n fabric").
As you noted, by default, \n in Python represents a newline character. To display \n as plain text, additional steps are required.
We need to escape the backslash (\) or use a raw string. Here are the steps:
- Escape the backslash (\\n)
print ("microsoft \\n fabric")
- Use a raw string (r"string")
- \\n: The double backslash \\ instructs Python to interpret \n as a literal \n instead of a newline character.
- r"...": The r prefix before a string denotes a raw string, which treats backslashes as literal characters.
If the suggestions provided do not resolve your issue, kindly share a snippet of the exact code you are using for encoding, decoding, and updating the notebook. With more context, I can assist further in debugging.

And if my answer was helpful, I'd really appreciate a 'Kudos'.
Hi chetanhiwale ,
Thanks for the details. It seems the issue is happening during the decoding process, where extra escape characters (\ and \n) are being added to the notebook content.
Here’s a step-by-step approach to fix it.
-
Ensure the base64-decoded string is handled correctly. Sometimes, decoding can introduce extra escape characters, especially if the payload is treated as a raw string. Use Python's base64 library to decode the payload and then process it as a string.
-
After decoding, clean up the extra escape characters by replacing them appropriately. For instance, you can use Python's replace() function to handle \\n and \\.
-
This will ensure the newlines and backslashes are correctly formatted.
-
Before sending the updated content back via the REST API, make sure the payload is re-encoded properly. Use the base64 library to encode the cleaned payload.
-
After making these changes, test the updated payload by sending it through the REST API and verify that the notebook content is correctly formatted without extra escape characters.
You can try these steps and let me know if you need any additional details.

Hello V-yubandi-msft , thanks for your input. I am using base64 for encoding and decoding the notebook defination. I have replace the extra characters like \\\' , \\\\\\\ with ' and \\. I am not able to handle \n condition.After updating the notebook , the \n is consider as next line. Simple example can be
print("microsoft \n fabric"),
after updating the notebook it becomes,
print("microsoft \
fabric")
Please share thoughts on this !!
