Data Conversion in SSIS

what is the use of Data Conversion

please give me an example

Hi

BOL: "The Data Conversion transformation converts the data in an input column to a different data type and then copies it to a new output column. For example, a package can extract data from multiple sources, and then use this transformation to convert columns to the data type required by the destination data store. You can apply multiple conversions to a single input column. "

For example, I used it when the DataSource date column was treated as a string , but I needed it to be converted to Datatime , or input column was INT datatype, but I needed to populate BIGINT destination column.
