DESCRIPTION

Spreadsheet::ParseExcel makes you to get information from Excel95, Excel97, Excel2000 file.

Functions

new
$oExcel = new Spreadsheet::ParseExcel( [ CellHandler => \&subCellHandler, NotSetCell => undef | 1, ]); Constructor.
CellHandler (experimental)
specify callback function when a cell is detected. subCellHandler gets arguments like below: sub subCellHandler ($oBook, $iSheet, $iRow, $iCol, $oCell); CAUTION : The atributes of Workbook may not be complete. This function will be called almost order by rows and columns. Take care almost, not perfectly.
NotSetCell (experimental)
specify set or not cell values to Workbook object.
Parse
$oWorkbook = CW$oParse->Parse($sFileName [, $oFmt]); return Workbook object. if error occurs, returns undef.
$sFileName

$oFmt
Formatter Class to format the value of cells.
ColorIdxToRGB
$sRGB = CW$oParse->ColorIdxToRGB($iColorIdx); ColorIdxToRGB returns RGB string corresponding to specified color index. RGB string has 6 charcters, representing RGB hex value. (ex. red = 'FF0000')

Format index number of that cell converts original text into applicatable for Value.
$oSelf
Formatter itself
$sText

$oSelf
Formatter itself
$oCell
Cell object
$oBook
Workbook object get format string for the $oCell.
$oSelf
Formatter itself
$oCell
Cell object
$oBook
WorkBook object contains that cell

KNOWN PROBLEM

This module can not get the values of fomulas in Excel files made with Spreadsheet::WriteExcel. Normaly (ie. By Excel application), formula has the result with it. But Spreadsheet::WriteExcel writes formula with no result. If you set your Excel application Auto Calculation off. (maybe [Tool]-[Option]-[Calculation] or something) You will see the same result.
