I am importing data in a CSV to Azure Table Storage using the Azure Storage Explorer application
I also repro the issue with Azure Storage Explorer.
As I know that Azure Storage Explorer is not actively maintained for long time.
It works correctly for me with Microsoft Azure Storage Explorer. Please have a try to use Microsoft Azure Storage Explorer, it may work correctly if the CSV file is not over limitation. More info about Azure storage table limitation please refer to document.
Max size of a table entity 1M
Max number of properties in a table entity 252
Max size of a single table 500T
The following is my test result.
Update1:
If there is an entity that size is larger that 1M, then Microsoft Azure Storage Explorer tool also crashed for me. Please have a try to check whether there is a entity that size is large that 1M. If it is that case, the CSV file may not be import to the Azure storage table as table is limited that table entity size less than 1M.
We aslo can send our feedback to tool team, if we meet any problem.
