Hi @henrikingo,
I’d like to work on this issue.
I can add proper documentation and usage examples for JsonImporter, including:
• A brief overview of its purpose
• Setup/usage instructions
• Code examples demonstrating common use cases
• Any relevant edge cases if applicable
Please assign this issue to me. I’ll start working on it right away and submit a PR once it’s ready.
Thank you!

You are welcome to work on this. The assignment field shouldn't be taken too seriously, although I will assign it to you. What matters is to submit a PR. Then it is clear you are working on it.

I’ve opened a PR adding detailed documentation and usage notes for JsonImporter.
Please let me know if any adjustments are needed.

Hi @Phanindra899 , I see you're working on this and have already added some changes! If you need a second pair of eyes for testing or a code review once you're done, I'd be happy to help out. Otherwise, great work!

Hey @tejrai07, sorry for the late reply! Thanks a lot for the offer.

Hi @henrikingo, sorry about that! I realized the previous PR had some unintended deletions. I'll go through the changes carefully this time and make sure only the documentation is added without touching any existing code. I'll submit a new PR soon. Thanks for the patience!
