# ElementSorter

Sort chemical elements by custom labels (e.g. R/M/X roles in
intermetallics), by Mendeleev number, or alphabetically. Custom labels
come from a dict or from an Excel file with `Binary`, `Ternary`, and
`Quaternary` sheets. New in cifkit 1.2.1 (migrated from
`bobleesj.utils`). See the
[OLED tutorial](../tutorials/oled) for elemental-data context.
