About NMEA 0183 (.nmea)

NMEA 0183 is the raw ASCII sentence stream a GPS receiver emits over serial — the lowest-common-denominator log format, with no route or metadata structure. Produced by marine GPS units and basic GPS loggers; read by almost anything that talks to a GPS receiver directly.

About Microsoft Excel (.xlsx)

Excel is a binary spreadsheet — one row per position, one column per field — the shortest path from a GPS track to a table you can sort, filter and chart. RouteConverter reads and writes both the legacy .xls and the modern .xlsx generation. Opened by Microsoft Excel, LibreOffice Calc, Numbers and Google Sheets — wherever GPS data needs analysing rather than navigating.
