This Video explains Json objects parsing techniques, which are as under: 1. Xpath: Extracts the JSON data based on the XPath query. 2. JsonPath: Extracts the JSON data based on the JSONPath query. Note that it is recommended to read the data by JSONPath in order to gain better performance. 3. JsonPath without loop: Extracts the JSON data based on the JSONPath query without setting a loop node.

Thanks for this good tutorial and Is it possible to add the schema dynamically like if we are parsing multiple files with different schema without creating metadata for each file???

Possible in Talend Enterprise Version!

So if we can't parse the data in the first place itself then we need to do it in 2 steps as per your last scenario and there is no other way for the same. Please correct me. Can you explain us how can I merge all the fields in one file?

How will you handle if the Json element is null while parsing the element.
@rajan4083 жыл бұрын
At that time we will have path not found exception

Thanks for your comment. The best practice is to split this file into smaller files and process them accordingly.
