Reads rows of table from one sheet of an Excel spreadsheet file.

During reading from cells, data conversion is performed according to following rules:

• if destination column is string type, numeric cell is converted to their string representation, boolean cell is converted to "true" or "false" string.
• if destination column is numeric type (integer, long or float), text cell is converted to this type if possible, otherwise null is assigned, boolean cell is converted to 1 or 0. Text as number can contain thousand separators, decimal point, sign and exponent, for example "1.234e+4" can be successfully converted to integer value 12340. Characters "," and "." is assumed as thousand or decimal point, so, for example values "-71,716.23" and "-71.716,23" can be successfully converted to the same float value -71716.23.
• if destination column is boolean type, text cell with value "true" or "1" or "false" or "0" is converted, numeric cell with value 1 or 0 is converted, otherwise null is assigned.
• if destination column is day or datetime type, text cell is parsed for date according to pattern "yyyy-MM-dd[t[hh:mm:ss]]", otherwise null is assigned.
