Hi, I've run into another weird Excel file that causes an error in exceljs:
TypeError: Cannot read property '0' of null at Object.decodeAddress (/Users/andreaslind/work/exceljs/lib/utils/col-cache.js:95:33) at Object.decodeEx (/Users/andreaslind/work/exceljs/lib/utils/col-cache.js:156:21) at /Users/andreaslind/work/exceljs/lib/xlsx/xform/book/workbook-xform.js:182:34 at Array.forEach (<anonymous>) at Object.each (/Users/andreaslind/work/exceljs/lib/utils/under-dash.js:7:13) at module.exports.reconcile (/Users/andreaslind/work/exceljs/lib/xlsx/xform/book/workbook-xform.js:175:7) at module.exports.reconcile (/Users/andreaslind/work/exceljs/lib/xlsx/xlsx.js:91:19) at /Users/andreaslind/work/exceljs/lib/xlsx/xlsx.js:345:16 at <anonymous>
The error is triggered by thisxl/workbook.xml (slightly edited and pretty-printed):

The fragments are passed tocolCache.decodeAddress, which assumes that there's a row number in each of the references ($B and$F). I can't tell if this syntax is legal or not -- I don't really know much about the .xlsx file format.
I tried to create a spec that triggers the error, but it seems that basing it off
scenarios inhttps://github.com/guyonroche/exceljs/blob/master/spec/unit/xlsx/xform/book/workbook-xform.spec.js doesn't work as that does not exercise the reconciliation phase.
The enclosed change avoids the error by makingdecodeAddress do a "best effort" when handed this kind of weird reference. I honestly don't know if that is the right way to go about it.
Unfortunately, I'm unable to share the original .xlsx file that triggered the error.
