What is a .XLN file?
XLN is a drill file describing the holes to make in a printed circuit board.
- Did you know
- Drill files tell the factory the position and size of every hole in a board.
- An XLN drill file follows the Excellon format, the de facto standard that drives the CNC machines drilling holes in circuit boards.
- The .xln extension is most associated with the EAGLE PCB design software.
- What Analyser reads
- Open scientific, medical and engineering files: DICOM scans, NIfTI brain volumes, Garmin FIT/TCX activities, FITS astronomy frames, FASTA/FASTQ sequences, chemistry structures (MOL/SDF/MOL2/CIF/XYZ), Gerber/Excellon PCB data, SPICE netlists, EDF/BDF biosignals, JCAMP-DX spectra, SPSS/Stata/SAS datasets and VTK/ParaView meshes - metadata extracted entirely in-browser.
- Depth of analysis
- .XLN is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .XLN file
- Drag a .XLN file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
