Release 5.10.2

Add:

Advanced_xlsx,py:
It was observed that sometimes the xls files did not have a sheet name. Therefore, a default value of "Sheet1" was set for those cases.
The rows were being encoded in latin-1 but then decoded in utf-8. A correction was applied by adding a select option to the "Open xls" and "Convert xls to xlsx" commands to choose between latin-1 and utf-8 encoding (if none is selected, latin-1 is used by default).
ReadRange: It is observed that the command only returns information when a range of cells is provided. If only a single cell is specified, for example A1, no information is retrieved. A correction has been applied.
