Can you please let me know , if this feature is available in AEM 6.2 "or" not.
Adobe Experience Manager Help | Using Metadata Import and Export in AEM Assets
This doc says this applies to 6.4.
Yes I know this feature applies to 6.4...
So my question is that , Is similar feature available in AEM 6.2 ?
No this feature is not avalible in AEM 6.2 you need to write custom code you can check acs-commons it has a feature to export metadata in csv format
AEM 6.4 :
There is not OOTB functionality in AEM 6.2 but it is available in AEM 6.4
If you are using acs-commons then you can use CSV Asset Importer, check below link
CSV Asset Importer
There are so many open source tools are available in the market to convert CSV to excel, so you can use those along with the ACS-Commons CSV Asset Importer.
I prefer this for single time execution or multiple times because it involves a manual approach
Custom solution :
If you want to avoid converting CSV to Excel using a tool and you want to run this as cron job then it is better to write custom job
