If doc file exist remove

I need help running a script. I have the script looking into a folder and converting .doc files to .odt. The script works fine except that I want it to only run when .doc files are present. If I can do this then I can put .xls files and .ppt files in the folder and convert them when they are detected.

This is what I currently have:

#! /bin/bash
for file in *.doc
    do
    if [ -e "*.doc" ]
        then
        mkdir ./ODT
        python /opt/DocumentConverter/DocumentConverter.py "${file}" "${file}".odt
        for i in *.odt; do j=`echo $i | sed 's/doc.odt/odt/g'`; mv "$i" ./ODT/"$j"; done
    fi   
done

Thanks!

you don't need the 'if [ -e ".doc" ]' (and the matching 'fi) - you will not go into the outter 'for' loop if there's nothing match against '.doc'

Actually I need to identify what type of files exist within the folder or it makes necessary folders:

#! /bin/bash
##
soffice -headless -accept="socket,port=8100;urp;"
for file in *.doc
	do
	mkdir ./ODT
	python /opt/DocumentConverter/DocumentConverter.py "${file}" ./ODT/"${file}".odt
	for i in *.odt; do j=`echo $i | sed 's/doc.odt/odt/g'`; mv "$i" "$j"; done    
done

for file in *.xls
	do
	mkdir ./ODS
	python /opt/DocumentConverter/DocumentConverter.py "${file}" ./ODS/"${file}".ods
	for i in *.ods; do j=`echo $i | sed 's/xls.ods/ods/g'`; mv "$i" "$j"; done    
done

for file in *.ppt
	do
	mkdir ./ODP
	python /opt/DocumentConverter/DocumentConverter.py "${file}" ./ODP/"${file}".odp
	for i in *.odp; do j=`echo $i | sed 's/ppt.odp/odp/g'`; mv "$i" "$j"; done    
done

for file in *.odt
	do
	mkdir ./DOC
	python /opt/DocumentConverter/DocumentConverter.py "${file}" ./DOC/"${file}".doc
	for i in *.doc; do j=`echo $i | sed 's/odt.doc/doc/g'`; mv "$i" "$j"; done    
done

for file in *.ods
	do
	mkdir ./XLS
	python /opt/DocumentConverter/DocumentConverter.py "${file}" ./XLS/"${file}".xls
	for i in *.xls; do j=`echo $i | sed 's/ods.xls/xls/g'`; mv "$i" "$j"; done    
done

for file in *.odp
	do
	mkdir ./PPT
	python /opt/DocumentConverter/DocumentConverter.py "${file}" ./PPT/"${file}".ppt
	for i in *.ppt; do j=`echo $i | sed 's/odp.ppt/ppt/g'`; mv "$i" "$j"; done    
done
