Function Convert-XlRangeToImage { <# .Synopsis Gets the specified part of an Excel file and exports it as an image .Description Excel allows charts to be exported directly to a file, but can't do this with the rest of a sheet. To work round this this function * Opens a copy of Excel and loads a file * Selects a worksheet and then a range of cells in that worksheet * Copies the select to the clipboard * Saves the clipboard contents as an image file (it will save as .JPG unless the file name ends .BMP or .PNG) * Copies a single cell to the clipboard (to prevent the "you have put a lot in the clipboard" message appearing) * Closes Excel #> Param ( #Path to the Excel file [parameter(Mandatory=$true)] $Path, #Worksheet name - if none is specified "Sheet1" will be assumed $workSheetname = "Sheet1" , #Range of cells within the sheet, e.g "A1:Z99" [parameter(Mandatory=$true)] $range, #A bmp, png or jpg file where the result will be saved $destination = "$pwd\temp.png", #If specified opens the image in the default viewer.
