How to update my changes to my dataset without command lines

I had a summarization dataset in the hub i downloaded it and did some preprocessing to it. I am wonder how to commit this update to my main repo!
Is there any commnads or method i can run in the notebook. I am not very good with git commands. thanks in advance.

You can use dataset.push_to_hub to push the files to a dataset repo programmatically.

rephrase me issue is i have a dataset called x that contains only train i donwload it and did some preproecssing and split it into test,valid and train how to upload this not to a new dataset but for my original one!
