npm install --save cellref
const cellref = require('cellref')
cellref.toR1C1('BU59') // will return R59C73const cellref = require('cellref')
cellref.toA1('R59C73') // will return BU59const cellref = require('cellref')
cellref('R59C73') // will return BU59
cellref('BU59') // will return R59C73If an invalid cell reference (not A1 or R1C1 notation) is passed as an argument to any of cellref functions, an Error will be thrown.
