        <pre>Confirmed.

RuntimeException is thrown when I use either of "Excel A1" or "Excel R1C1"

I put some SAL_INFO macros to see what's happening. Though I haven't looked the
source closer,

<a href="https://opengrok.libreoffice.org/xref/core/sc/source/core/tool/address.cxx?r=1250aecd&fi=ConvertSingleRef#1149">https://opengrok.libreoffice.org/xref/core/sc/source/core/tool/address.cxx?r=1250aecd&fi=ConvertSingleRef#1149</a>

SAL_INFO("sc.core", OUString(p)); showed $Sheet1.$A$1 for "Calc A1", 
SAL_INFO("sc.core", OUString(p)); showed Sheet1!$A$1 for both "Excel A1" and
"Excel R1C1".

This can be problematic here, I guess.
