[FIX] xlsx: export array formula

[LucasLefevre]

Strange Excel Online behavior: =TRANSPOSE(A1:A10) seem to be exported as {=TRANSPOSE(A1:A10)} and the array can't be modified. Same behavior if exporting from GSheet and importing to excel online

When exporting from Excel Online, the cell has properties in a futureMetadata tag, looks like they are using a more recent file format version.
