It is good practice to format your fields directly within the FDF file as you would like the data to appear in your output PDFs. If you are flattening formatted form fields (e.g. “currency”), you will need to include the entire data string for that value in your FDF file. For example, if the value of the field is to be $1,234.00 in the output PDF file, the value in the FDF file needs to be /V ($1,234.00). The value /V (1234) in the FDF file will appear in the flattened PDF file as 1234. FDFMerge and FDFMerge Lite have a new command line feature, -norebuild, which can be used to allow for formatting of merged fields. However, this feature will not work on stamped fields.
