Hi Team ,

We want to rename column name of doc before indexing.  
Please find below example :

![before index](https://us1.discourse-cdn.com/elastic/original/3X/0/f/0fcce5517f1732507c2cd696a9ef79d9512c72aa.png)

in above example we have **tag.customer\_id** column name and we want to rename it to **customerID** before indexing doc as below.

![after rename](https://us1.discourse-cdn.com/elastic/original/3X/e/1/e1e57a42c3836c23be08455a67b89bb2fba29fe1.png)

in future data will come as **tag.customer\_id** but it should index as **customerID**

Please suggest how to use pipeline for this.

Thanks & Regards,  
Jalpesh
