Question

Answer 1

Hi

Thanks for reaching out to Microsoft Q&A.

I believe you are trying to edit and append the data from azure portal. Pls note that you cannot edit a file of size more than 2.05MB from azure portal. But this is not related to the file size you upload, the restriction is only for editing.

@kaja sherief Welcome to Microsoft Q&A! Thank you for posting your query.
Adding more information to the above response!

The best and easiest option to make changes/edit/update csv file in the Azure Storage explorer tool.

There is a limit of editing file in Azure portal. You can just edit a file in portal which size is under 2.1MB. You can refer here for the limit

Complete details of Azure Block blobs

You can view/download csv file in using Azcopy Azure Storage Explorer tool or Azure Data factory

The limits cannot be changed because it's designed. If you still want to expand the size of editing file in Azure portal which uploaded/Downloaded into a blob, you can post your idea in the user voice forum.
