The CSP supports the submission of CSV files encoded in UTF-8 format. Occasionally, in CHESS Replacement technical documentation, excel files containing sample data are provided for information purposes. Users are reminded to re-create the data in a UTF-8 CSV file format, rather than submitting the original file itself.
In a UTF-8 BOM encoded CSV, it is possible for the file to contain a Byte Order Mark (BOM) character. If this character is present, it is treated as an invalid file format by the CSP and the submission may fail due to various reasons such as a NullPointerException.
