Not able to import "Time Spent" (Worklog) while bulk import issues from CSV

[ads.yramesh]

When I try to import multiple issues (work items) into Jira Cloud using CSV (as a regular user), I am not able to import data for "Time Spent". Even if I mention "Time Spent" in seconds in CSV file, it is not reflecting in the Issues that are created.

However, if I import issues as a Jira Admin using External System Import, I am able to import the "Time Spent" data through CSV. 

Can someone please help on this issue?
Thanks

Hello @ads.yramesh ,
Welcome to the Community !
Yes, there are certain data that cannot be imported via Bulk issue import (regular user import action). 
To import time spent (work log), then external system import to be used. Alternate, you may create a python script or etc/ to update the data via csv input with the help of API (check for availability of those) - https://developer.atlassian.com/cloud/jira/platform/rest/v2/intro/
 
Here's the info about CSV import  - https://confluence.atlassian.com/adminjiraserver0822/importing-data-from-csv-1142237802.html
