PRN files that contain table data are completely unsuitable for viewing and editing. This format is weakly supported by popular programs, and the only way to access information in such files is to convert PRN to XLS format. Becoming an Excel spreadsheet, the file can be edited in MS Excel. Total PDF ConverterX will perform such conversion from the command line.
Command line mode has a few differences from traditional GUI:
Conversions are done in silent mode (no popup windows, progress bar, etc.)
Command is sent to a script on a web server, not on your PC
A few users can convert files using one single program
Total PDF ConverterX is a web application that can work either on local server or as an online service available from the Internet. Using ActiveX this program can be integrated into a custom graphic interface to make it easily accessible for common users. It is possible to convert PRN to XLS via command line in batches, grouping source files for faster processing. You do not need to copy sources somewhere for conversion. Just specify their location in conversion command parameters. It will be better to store sources in one folder. The batch PRN XLS server converter is able to work automatically. In this mode you don't even need to send commands. However, such configuration requires additional tool - Total Folder Monitor.
Total PDF ConverterX makes it possible to convert only text information from original files, skipping images. This PRN XLS converter automatically does both data sorting and conversion in one step. Every page can be transformed into a separate Excel file, or all sources can be joined into one result copy.
You can test all these options in your environment for free. The script is easy to install and setup for specific requirements. Download it for trial use here.
