Hi I'm Ambarish, a SAP Business One Global Certified professional from India. I have been working as a SAP Business One Consultant for last 3 years. As I understand is that you are using some kind of Accounting & business management software and now you need to transfer existing data to SAP business One. SAP Support CSV, Text and Excel format for Data Import… CSV (Comma Separated Value) is ideal. For each modules, they provide excel templates for data transferring.. We need to arrange our existing data as per the corresponding template before transfer to SBO I think I can help you on this… Thanks & Regards Ambarish
