xlsData (Function)
In french: xlsDonnée
Retrieves the content of a cell found in an XLS file. The result depends on the opening mode of XLS file:
  • In multi-sheet mode, the data retrieved is found on the worksheet selected by xlsCurrentWorksheet.
  • In compatible mode, the data retrieved is always found on the first worksheet of the workbook.
Remark: The content of a cell found in an XLS file can be retrieved if:
  • The XLS file exists.
  • The XLS file is opened.
// Declare the variables
ResData is string
XLSFileID is int
 
// Open an XLS file
XLSFileID = xlsOpen("C:\MyDirectory\File.XLS")
IF XLSFileID <> -1 THEN
// Retrieve the value of a cell
ResData = xlsData(XLSFileID, 3, 4)
...
END
cMyXLSFile is xlsDocument
 
cMyXLSFile = xlsOpen(sMyFile, xlsWrite)
IF ErrorOccurred = False THEN
Azz is int = xlsCurrentWorksheet(cMyXLSFile)
Info("Current worksheet in the Excel file: " + Azz)
// Change worksheet
IF xlsCurrentWorksheet(cMyXLSFile, 2) = True THEN
Info("The current worksheet was modified.")
// Read a cell for test
Info(xlsData(cMyXLSFile, 11, 2))
ELSE
Error("The selected file does not include a second worksheet!")
END
ELSE
Error(ErrorInfo(errFullDetails))
END
xlsClose(cMyXLSFile)

Remarks

Content of the cells: taking the empty rows and columns into account

The empty rows and columns can be taken into account or not. For example:
xlsData(XLSFileID, 2, 3, True)
// Return the content of D2 cell: "23"
xlsData(XLSFileID, 2, 3, False)
// Return the content of C2 cell: ""
In this example, the column C (that is entirely empty) can be taken into account or not.

xlsData throws an error in the following cases:
  • The specified row and/or column is empty.
