Subject [Bug 57390] Match function with array argument in formula results in "File error: data may have been lost"

--- Comment #5 from Nick Burch <apache@gagravarr.org> ---
That's the bug, yes. There are basically 5 tasks:
 * Get the FormulaParser to be able to generate the correct (same as Excel)
Ptgs for an array formula
 * Get HSSFFormulaParser.toFormulaString able to correctly turn those Ptgs back
into the formula string
 * Get HSSFFormulaEvaluator to process the array ptgs correctly
 * Get XSSFFormulaEvaluator to process the array ptgs correctly
 * Get the Match function to handle the array ptgs correctly

I'm not sure how many of those are currently sorted by the work on bug #48292
and friends, but that's roughly "all" you need to do...
