From Hacker Dude-san:
PDB Converter is a Windows 95/98/98SE/Me/NT/2000/XP application that can create NSBasic/Palm-compatible PDB files interactively (by direct data entry into its spreadsheet) or by converting existing text files (including tab-delimited files), quoted and non-quoted comma separated values (CSV) files, and Excel 4.0 and 5.0 worksheets. PDB Converter offers powerful spreadsheet editing features, and produces keyed and non-keyed database (PDB) files directly readable by applications written using NSBasic/Palm™. Once loaded into the Palm™ device, all of the usual NSBasic™ functions used for manipulation of databases can be used on these files. Any other program that uses PDB files created using PalmDB.DLL should be able to read and write PDB files created by PDB Converter. Conversely, PDB Converter can take these PDB databases and convert them to Excel 4 or 5 worksheets, quoted or non-quoted CSV files, tab-delimited or simple text files, HTML tables, and complete HTML web pages with embedded tables.
