Run ffmpeg on all files of a folder [duplicate] - ffmpeg

Question

I need to convert some xls files into xlsx files. I can successfully convert one xls file into xlsx by running this command into cmd prompt (windows):
ssconvert inputFileName.xls outputFileName.xlsx
(ssconvert is a Gnumeric's command-line utility that can convert between different spreadsheet file formats)
I'd like to write a batch file that FOR EACH file in a specified directory runs the command I wrote above, using the current file name both for input and for output filename.
For example, if I have this set of files:
c:\directory\file1.xls
c:\directory\file2.xls
c:\directory\file3.xls
the output should be
c:\directory\file1.xlsx
c:\directory\file2.xlsx
c:\directory\file3.xlsx
so the batch pseudo code should be something like
directory = c:\directory\
for (fileName in directory)
ssconvert fileName.xls fileName.xlsx
Can anyone help me?

for /r %%v in (*.xls) do ssconvert "%%v" "%%vx"
a couple have people have asked me to explain this, so:
Part 1: for /r %%v in (*.xls)
This part returns an array of files in the current directory that have the xls extension. The %% may look a little curious. This is basically the special % character from command line as used in %PATH% or %TEMP%. To use it in a batch file we need to escape it like so: %%PATH%% or %%TEMP%%. In this case we are simply escaping the temporary variable v, which will hold our array of filenames.
We are using the /r switch to search for files recursively, so any matching files in child folders will also be located.
Part 2: do ssconvert "%%v" "%%vx"
This second part is what will get executed once per matching filename, so if the following files were present in the current folder:
c:\temp\mySheet.xls,
c:\temp\mySheet_yesterday.xls,
c:\temp\mySheet_20160902.xls
the following commands would be executed:
ssconvert "c:\temp\mySheet.xls" "c:\temp\mySheet.xlsx"
ssconvert "c:\temp\mySheet_yesterday.xls" "c:\temp\mySheet_yesterday.xlsx"
ssconvert "c:\temp\mySheet_20160902.xls" "c:\temp\mySheet_20160902.xlsx"

Answer 2

Actually this is pretty easy since Windows Vista. Microsoft added the command FORFILES
in your case
forfiles /p c:\directory /m *.xls /c "cmd /c ssconvert #file #fname.xlsx"
the only weird thing with this command is that forfiles automatically adds double quotes around #file and #fname. but it should work anyway

Answer 3

you can run something like this (paste the code bellow in a .bat, or if you want it to run interractively replace the %% by % :
for %%i in (c:\directory\*.xls) do ssconvert %%i %%i.xlsx
If you can run powershell it will be :
Get-ChildItem -Path c:\directory -filter *.xls | foreach {ssconvert $($_.FullName) $($_.baseName).xlsx }

I am doing similar thing to compile all the c files in a directory.
for iterating files in different directory try this.
set codedirectory=C:\Users\code
for /r %codedirectory% %%i in (*.c) do
( some GCC commands )
