Hi, guys, I hope this article can help you quickly convert XLS to grayscale image. The method I would like to introduce is to use an all-to-all document converter to convert XLS to grayscale image via command line. The document converter is named VeryPDF Document Converter or docPrint Pro. The whole process requires three steps.
First, please download VeryPDF Document Converter. VeryPDF Document Converter can convert XLS to more than a hundred image file formats. That’s pretty cool! After you install it on your computer, you can find an executable file named doc2pdf in the installation directory, and this executable file is just the command line application you are going to use in the following steps. Anyway, after this tool is installed, you can go to the next step.
Second, you should open the command prompt window. If you are a command line user, you don’t need to read the introduction of this step. If you are not very familiar with command line, please go on reading. Different Windows operating systems will require different ways to open the command prompt window. In Windows XP, please click Start on the left end of the task bar, and then please click Command Prompt. ln Windows 7 or Vista, you should click Start, type cmd in the search box on the Start menu, and then press Enter.
Third, as soon as the command prompt window appears on the screen, you should type a command line in it. The following usage and option of the executable file, and examples may be helpful.
- Usage：doc2pdf [options] <-i Document Files> [-o Output]
- Options: -y : create 8-bit grayscale image file
- Examples:
- doc2pdf -y -i C:\input.xls -o D:\output.esp
