Spreadsheet::XLSX::Utility exports utility functions concerned with Excel format setting. ExcelFmt is used by Spreadsheet::XLSX::Fmt2007.pm which is used by Spreadsheet::XLSX. Functions This module can export 3 functions: ExcelFmt, ExcelLocaltime and LocaltimeExcel. ExcelFmt $sTxt = ExcelFmt($sFmt, $iData [, $i1904]); $sFmt is a format string for Excel. $iData is the target value. If $flg1904 is true, this functions assumes that epoch is 1904. $sTxt is the result. For more detail and examples, please refer sample/chkFmt.pl in this distribution. ex. ExcelLocaltime ($iSec, $iMin, $iHour, $iDay, $iMon, $iYear, $iwDay, $iMSec) = ExcelLocaltime($iExTime [, $flg1904]); ExcelLocaltime converts time information in Excel format into Perl localtime format. $iExTime is a time of Excel. If $flg1904 is true, this functions assumes that epoch is 1904. $iSec, $iMin, $iHour, $iDay, $iMon, $iYear, $iwDay are same as localtime. $iMSec means 1/1,000,000 seconds(ms). LocaltimeExcel $iExTime = LocaltimeExcel($iSec, $iMin, $iHour, $iDay, $iMon, $iYear [,$iMSec] [,$flg1904]) LocaltimeExcel converts time information in Perl localtime format into Excel format . $iSec, $iMin, $iHour, $iDay, $iMon, $iYear are same as localtime. If $flg1904 is true, this functions assumes that epoch is 1904. $iExTime is a time of Excel. col2int $iInt = col2int($sCol); converts a excel row letter into an int for use in an array This function was contributed by Kevin Mulholland. int2col $sCol = int2col($iRow); convert a column number into column letters NOET: This is quite a brute force coarse method does not manage values over 701 (ZZ) This function was contributed by Kevin Mulholland. sheetRef ($iRow, $iCol) = sheetRef($sStr); convert an excel letter-number address into a useful array address NOTE: That also Excel uses X-Y notation, we normally use Y-X in arrays $sStr, excel coord (eg. A2). This function was contributed by Kevin Mulholland. xls2csv $sCsvTxt = xls2csv($sFileName, $sRegion, $iRotate); convert a chunk of an excel file into csv text chunk $sRegions = "sheet-colrow:colrow" (ex. '1-A1:B2' means 'A1:B2' for sheet 1) $iRotate = 0 or 1 (output should be rotated or not) This function was contributed by Kevin Mulholland. AUTHOR
