My .Net application needs to convert a PDF document to Word format programmatically.
I evaluated several products and found Acrobat X Pro, which gives a save as option where we can save the document in Word/Excel format. I tried to use Acrobat SDK but couldn't find proper documentation from where to start.
I looked into their IAC sample but couldn't understand how to call the menu item and make it execute the save as option.

Answer 1

You can do this with Acrobat X Pro, but you need to use the javascript API in c#.
AcroPDDoc pdfd = new AcroPDDoc();
pdfd.Open(sourceDoc.FileFullPath);
Object jsObj = pdfd.GetJSObject();
Type jsType = pdfd.GetType();
//have to use acrobat javascript api because, acrobat
object[] saveAsParam = { "newFile.doc", "com.adobe.acrobat.doc", "", false, false };
jsType.InvokeMember("saveAs",BindingFlags.InvokeMethod | BindingFlags.Public | BindingFlags.Instance,null, jsObj, saveAsParam, CultureInfo.InvariantCulture);
Hope that helps.

I did something very similar using WinPython x64 2.7.6.3 and Acrobat X Pro and used the JSObject interface to convert PDFs to DOCX. Essentially the same solution as jle's.
The following should be a complete piece of code that converts a set of PDFs to DOCX:
# gets all files under ROOT_INPUT_PATH with FILE_EXTENSION and tries to extract text from them into ROOT_OUTPUT_PATH with same filename as the input file but with INPUT_FILE_EXTENSION replaced by OUTPUT_FILE_EXTENSION
from win32com.client import Dispatch
from win32com.client.dynamic import ERRORS_BAD_CONTEXT
import winerror
# try importing scandir and if found, use it as it's a few magnitudes of an order faster than stock os.walk
try:
from scandir import walk
except ImportError:
from os import walk
import fnmatch
import sys
import os
ROOT_INPUT_PATH = None
ROOT_OUTPUT_PATH = None
INPUT_FILE_EXTENSION = "*.pdf"
OUTPUT_FILE_EXTENSION = ".docx"
def acrobat_extract_text(f_path, f_path_out, f_basename, f_ext):
avDoc = Dispatch("AcroExch.AVDoc") # Connect to Adobe Acrobat
# Open the input file (as a pdf)
ret = avDoc.Open(f_path, f_path)
assert(ret) # FIXME: Documentation says "-1 if the file was opened successfully, 0 otherwise", but this is a bool in practise?
pdDoc = avDoc.GetPDDoc()
dst = os.path.join(f_path_out, ''.join((f_basename, f_ext)))
# Adobe documentation says "For that reason, you must rely on the documentation to know what functionality is available through the JSObject interface. For details, see the JavaScript for Acrobat API Reference"
jsObject = pdDoc.GetJSObject()
# Here you can save as many other types by using, for instance: "com.adobe.acrobat.xml"
jsObject.SaveAs(dst, "com.adobe.acrobat.docx") # NOTE: If you want to save the file as a .doc, use "com.adobe.acrobat.doc"
pdDoc.Close()
avDoc.Close(True) # We want this to close Acrobat, as otherwise Acrobat is going to refuse processing any further files after a certain threshold of open files are reached (for example 50 PDFs)
del pdDoc
if __name__ == "__main__":
assert(5 == len(sys.argv)), sys.argv # <script name>, <script_file_input_path>, <script_file_input_extension>, <script_file_output_path>, <script_file_output_extension>
#$ python get.docx.from.multiple.pdf.py 'C:\input' '*.pdf' 'C:\output' '.docx' # NOTE: If you want to save the file as a .doc, use '.doc' instead of '.docx' here and ensure you use "com.adobe.acrobat.doc" in the jsObject.SaveAs call
ROOT_INPUT_PATH = sys.argv[1]
INPUT_FILE_EXTENSION = sys.argv[2]
ROOT_OUTPUT_PATH = sys.argv[3]
OUTPUT_FILE_EXTENSION = sys.argv[4]
# tuples are of schema (path_to_file, filename)
matching_files = ((os.path.join(_root, filename), os.path.splitext(filename)[0]) for _root, _dirs, _files in walk(ROOT_INPUT_PATH) for filename in fnmatch.filter(_files, INPUT_FILE_EXTENSION))
# patch ERRORS_BAD_CONTEXT as per https://mail.python.org/pipermail/python-win32/2002-March/000265.html
global ERRORS_BAD_CONTEXT
ERRORS_BAD_CONTEXT.append(winerror.E_NOTIMPL)
for filename_with_path, filename_without_extension in matching_files:
print "Processing '{}'".format(filename_without_extension)
acrobat_extract_text(filename_with_path, ROOT_OUTPUT_PATH, filename_without_extension, OUTPUT_FILE_EXTENSION)

Adobe doesn't support PDF to Word conversions, unless you're using their Acrobat PDF client.
Maeaning you can't do it with their SDK nor by calling a command-line. You can only do it manually.
