Ragged right format in SSIS is a type of flat file format. It does not have a fixed width for each column or field. Instead, each row has data columns which are of varying lengths. This means that each row ends at the end of the longest data value present in that column. It is commonly used for text-based flat file formats such as CSV and tab-delimited files.
Ragged right format is suitable for data formats where the fields vary in length, such as employee name or address fields. It allows the data to be presented with spaces between fields to make it easier to read. It is not ideal for data formats where all fields should have the same width, as these will have to be padded with extra spaces which can cause storage and performance issues.
Using the ragged right format can be a good way to ensure that data is presented in a readable format and is easy to process. It is also useful as it avoids extra information on the headings and footers which can sometimes be found in flat files.
