HL7Tools 20.12.19

HL7 Tools contains multiple applications for working with HL7 message data.

HL7Viewer is a utility for viewing and editing HL7 data in an expandable/collapsible tree view (no more counting pipe characters!). With multiple messages loaded, it allows you to sort and filter the data on various criteria. You can do search and replace operations, making it quite easy to take a sequence of production messages and sanitize them so they can be replayed in a test environment.

HL7Script is for bulk-processing of messages for analysis or transformation. It has its own scripting language you can use to extract the information you need from the input messages. HL7Viewer tends to bog down when you start getting into the thousands of messages, but HL7Script has no problem processing hundreds of megabytes of data since it works on them one-at-a-time.

HL7ScriptService is the Windows service version of the interactive HL7Script program. It will periodically poll a directory for files containing HL7 messages and process them with a script. Multiple such connections can be configured, each set to poll a different directory and use different scripts and settings. It includes a graphical configuration program to make it easy to set up, HL7ScriptServiceConfig.exe.

HL7TransmitterService.exe is a Windows service that is used to transmit and receive HL7 messages using the Minimal Low-Level Protocol (MLLP) over TCP/IP connections. Multiple transmitters and receivers can be configured. It includes a graphical configuration program to make it easy to set up, HL7TransmitterConfig.exe.

HL7Sort is a command-line utility that will read an input file or directory full of HL7 messages and write them to an output file in a user-selected sorted order but otherwise unchanged. HL7Viewer is fine for sorting a few hundred messages, but HL7Sort can work on very large files.
