is it possible for order placement from excel using curl fyers api vba post code or query post ??? not able to place orders always getting error ??

Hi praveen chinni
Point is that if you somehow able to place request from Excel , so we will response for same.
For proper parameters query please read order placement section from our docs.
Docs link : https://myapi.fyers.in/docsv3

We don't provide excel plugins means there is no directly package or anything for excel where you can call our APIs.

Once try our Python SDK , You will get much better than excel. It is simple, No need of more coding background
