Owning Class: support

Requires: MathScript RT Module (Windows)


fwrite_xls(file, a)

fwrite_xls(file, a, sheet)

fwrite_xls(file, a, sheet, range)

Legacy Name: xlswrite


Writes data to a Microsoft Excel spreadsheet file.




Name Description
file Specifies the Excel file to which you want to write. file is a string.
a Specifies the data you want to write. a can be string or a numeric value in a scalar or a matrix.
sheet Specifies the spreadsheet in file to which you want to write. sheet can be an integer that specifies the index of a spreadsheet or a string that specifies the name of a spreadsheet. If you do not specify sheet, LabVIEW writes a to the first spreadsheet.
range Specifies the range of data in sheet you want to write. range is a string. The default is 'A1'.


To specify the range, you can use a cell number, such as 'A1', that specifies the top left cell at which to begin writing, or you can use a colon as a range operator. For example, you can specify 'A1:B3', where A1 and B3 specify the top left and bottom right cells to which you want to write data. If you use a colon as a range operator to specify the range and if the size of a is larger than the range, LabVIEW ignores the elements outside of the range.
