What is a .SBX file?

SBX is the companion index to a shapefile’s SBN spatial index.

Did you know
  • SBX works with SBN to speed up spatial searches in a shapefile.
  • SBX is the lightweight companion to the SBN index, pointing into it to speed shape lookups, and both are written only by Esri software.
  • Like the SBN it pairs with, the SBX format was never documented by Esri and is purely an optional accelerator for a shapefile.
What Analyser reads
Identify and read more GIS and mapping files: OpenStreetMap o5m/o5c binaries, Esri layer files (.lyrx ArcGIS Pro CIM JSON, .lyr ArcMap), QGIS projects (.qgs/.qgz - version, CRS, layer list), shapefile spatial indexes (.sbn/.sbx), GMT/GDAL colour palettes (.cpt) and ENVI band-interleaved rasters (.bil/.bip/.bsq).
Depth of analysis
.SBX 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 .SBX file
Drag a .SBX 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.
