Sort the TOC in ArcMap alphabetically

I wanted to quickly create a kmz for a client which contained all of their asset data. It didn’t need to be in any order, but then I thought, why not alphabetical?

# Sorts the TOC in ArcMap alphabetically using
# a temporary group layer for reference. This group
# layer should be empty, and can be created anywhere
# in the TOC.
#
# For use in the Python window in ArcMap.
#
import arcpy
mxd = arcpy.mapping.MapDocument("CURRENT")
df = arcpy.mapping.ListDataFrames(mxd)[0] # Assuming one data frame
group_lyr = [lyr for lyr in arcpy.mapping.ListLayers(mxd) if lyr.isGroupLayer][0] # The temp group layer should be the only one
lyr_names = sorted(lyr.name for lyr in arcpy.mapping.ListLayers(mxd) if lyr.isFeatureLayer)
for name in lyr_names:
arcpy.mapping.MoveLayer(df, group_lyr, arcpy.mapping.ListLayers(mxd, name)[0], "BEFORE")
arcpy.mapping.RemoveLayer(df, group_lyr)

After trying out a few different ways, I decided to use an empty group layer as the anchor layer for sorting. One cannot add a group layer to the table of contents via Python, so unfortunately that step is a manual exercise.

This still beats manually moving dozens of layers up and down though 🙂
