1. A method comprising: identifying, by a computer-based system for facilitating a transfer of data from a client database to a host database, at least one data field from said client database desired for said host database; incorporating, by the computer-based system, said data field in a spreadsheet; populating, by the computer-based system, at least a portion of said data field in said spreadsheet with assumed data values; developing, by the computer-based system, an algorithm configured to reformat data associated with said data field from said client database and desired for said host database; receiving, by the computer-based system, a test file from said client database; creating, by the computer-based system, a reformatted test file with said test file using said algorithm; comparing, by the computer-based system, said reformatted test file to said spreadsheet; identifying, by the computer-based system, a change, wherein said change would substantially conform said reformatted test file to said spreadsheet; creating, by the computer-based system, an updated algorithm from said algorithm which incorporates said at least one change; receiving, by the computer-based system, an input file from said client database; creating, by the computer-based system, a reformatted input file by applying said updated algorithm to said input file; and, uploading said reformatted input file to said host database.
