Removing commas and quotes from numeric fields in csv file using SSIS

Hi,

I am creating SSIS package which reads data from a csv file and stores in SQL Server database. There are a few numeric fields in the csv files. They sometimes contain value like"1,008.54"

How do I remove the quotes and comma from the value?

I have successfully separated the rows with this kind of data by using Conditional Split Transformation. (SUBSTRING([Column 9],1,1) == "\"")

After this, I tried using Derived Column Transformation to REPLACE comma and quotes with empty string. But it is not working.

Please advise.

Thanks!
