Parse an A1-style cell reference (e.g. "B3" or "$AA$100") into 1-based row and column numbers, plus the column letters and whether each part is absolute.
Convert between a spreadsheet column letter and its 1-based index in either direction. Provide exactly one of `letter` (e.g. "AA") or `number` (e.g. 27); the response always contains both.
Parse an A1 range like "A1:C10" into its start and end cells (normalized so start is the top-left) and its extent — row count, column count and total cell count.
Build an A1-style cell reference from 1-based row and column numbers, optionally marking the row and/or column absolute ($).
