Client Side windows Data extraction tool for oracle

Hi All,
We use cloud based managed oracle servers and don't have access to datapump or command line utilities neither to server directly.

I have tables with  25-50 million rows of data. I have access to oracle schema. I am looking for a pure client side data extraction tool to get millions of rows in a text file.

I have tried TOAD/Oracle SQL developer and files extracted have some strange chars in them which is breaking system while loading them.
Ideally the tool should make sure data downloaded could be uploaded easily. It should able to extract millions of rows using threading to reduce time and split files in small sizes like 2GB.

Any ideas?

You already mentioned the two tools that I know of.

>>and files extracted have some strange chars in them which is breaking system while loading them.

Then you might have a data or characterset issue.

If you are using multi-byte charactersets, set NLS_LANG on the client side:

Hi,
Before an extract I did set these parameters as well as NLS_DATE_FORMAT to make sure files are extracted clean. But they didn't come thru OK.

nls_date_format is only for date columns.  If your database is one characterset and your client set to another, this can easily cause a conversion issue with the data extract.  NLS_LANG is what handles the conversion or you.

Can you provide a sample of the before and after of the data that isn't extracing properly?

You don't have command line access to the utilities on the server, but what is wrong with running exp or expdp from the client?
