Error while load sharedString from file with merged cells

[baminmru]

test.xlsx

error found in function: internal SharedStrings(ZipArchive archive)

After load string sequence is worng if Excel file contain vertically merged cells.

I make some changes like this: foreach (XElement si in document.Descendants().Where(d => d.Name.LocalName == "si") ) { String s; s = ""; foreach (String X in si.Descendants().Where(d => d.Name.LocalName == "t")) { if (s != "") s += " "; s = s + X; } int i = AddString(s); System.Diagnostics.Debug.Print(s + ":" + i.ToString()); }
