Based on the terminology, this guide refers to the process of converting flight plans or navigation data from the (using the .xpl or proprietary formats often referred to as X-Plane Data Files, or simply "XDF" in community shorthand) into the KeyPoint ( .kp ) format used by older addons like PMDG , Level-D , or specific FMC software versions common around 2021.
A tuner may have a definition file in TunerPro (.xdf) but prefers the advanced analytical tools in WinOLS, necessitating a conversion to .kp. Interoperability: Because WinOLS uses a proprietary binary format, converting KP is notoriously difficult, whereas converting xdf to kp 2021

While direct “XDF to KP” conversion was not yet a one-click solution in 2021, the maturation of GDAL and QGIS made it feasible for technical users. If you are working with legacy XDF data today, following the 2021 methodology remains surprisingly effective, though newer 2024 tools (like PDAL 2.6+) now offer smoother pipelines.
