I have csv data file as below:

 `Column1`                  `Column2`                    `Column3`

{'name':'Mark Zuckerberg'} ,  {'first_name':'Mark'}  ,  {'last_name':'Zuckerberg'}

{'name':'Steve Jobs'}   ,    {'first_name':'Steve'}  , {'last_name':'Jobs'} 

I want my data as below using Talend Tool:

Steve Jobs       Steve          Jobs

Mark Zuckerberg  Mark          Zuckerberg

Steve Jobs       Steve         Jobs

Answer 1

You can use substring() and indexOf() functions to achieve this.

Explanation:

1. Since Key and Value is separated by : we can substring after the : and before }
2. To get the position of then : and } , we can use indexOf function

Below is the condition used in tMap for three columns,

row1.Column1.substring(row1.Column1.indexOf(":")+2, row1.Column1.indexOf("}")-1) 
row1.Column2.substring(row1.Column2.indexOf(":")+2, row1.Column2.indexOf("}")-1) 
row1.Column3.substring(row1.Column3.indexOf(":")+2, row1.Column3.indexOf("}")-1) 

Result,
