HL7 Soup Online Free Online Edition HL7 Editor & Viewer for Your Browser
Free online HL7 editor and viewer
HL7 Soup Online is the free hosted version of HL7 Soup: a practical HL7 editor, HL7 viewer, and HL7 parser that you can use directly in your browser. Open the online tool whenever you need to read, edit, validate, compare, anonymize, document, or test an HL7 v2 message.
The hosted edition is completely free to use. There is no software to install before you can explore a message, so it is useful for quick investigations, support calls, demonstrations, training, vendor conversations, and reviewing non-sensitive samples from Windows, macOS, Linux, a tablet, or a phone.
HL7 Soup Online combines the raw HL7 message with a plain-language story, a structured segment and field viewer, editing tools, validation, message comparison, anonymizing, interface definitions, and practical HL7 reference guidance. The different views stay connected, helping you understand what the message says instead of only showing pipes and carets.
A paid self-hosted edition is available for an additional cost when your organization needs the application and its processing inside your own environment, support for very large files, local data tables, or send-and-receive testing.
Privacy note: routine editing and analysis in the free hosted edition run in your browser, but you should not paste patient-identifiable, production, confidential, or regulated clinical data into any public website unless your organization has approved it. For sensitive data, use the paid self-hosted edition so the work stays under your control. See the Integration Soup privacy policy or contact support if you are unsure.
HL7 Soup Web is the paid self-hosted edition of HL7 Soup: a practical HL7 editor and HL7 viewer that runs in your browser while the application and server-side processing stay inside the environment your organization controls.
The self-hosted edition is designed for patient-identifiable or production data, very large HL7 files, local data tables, server-backed search and statistics, and MLLP/TCP or HTTP send-and-receive testing. It combines the raw message, plain-language story, field viewer, editor, validation, comparison, anonymizing, interface definitions, and HL7 reference guidance in one workspace.
The free hosted edition remains available at hl7soup.integrationsoup.com for quick reviews, training, demonstrations, support, and non-sensitive samples. Self-hosting is the paid option for local control, scale, and interface connectivity.
Privacy note: keep your self-hosted deployment within the governance, access controls, firewall rules, backups, and security reviews required by your organization. See the Integration Soup privacy policy or contact support if you are unsure.
Edit HL7 messages online
The raw HL7 editor keeps the real message visible while structured views help you make precise changes. Select a segment, field, component, or sub-component in one view and HL7 Soup follows the same location in the others.
- Open HL7 v2 messages or create a new message from a known message type.
- Edit delimiters, fields, components, repetitions, and line structure in the browser.
- Work with several message documents in tabs and download your updated content.
- Search and filter message sets when you need to find a particular value or field.
View and understand every field
The HL7 viewer turns each message into a clinical and operational story, then links that story back to the exact field that produced it. It is easier to explain an admission, order, result, referral, document notification, or scheduling update when the meaning and source stay together.
- Read the message story, raw HL7, segment grid, and field details side by side.
- See names and descriptions for message types, segments, fields, data types, and tables.
- Inspect fields such as MSH-9, PID-8, OBR-4, and OBX-3 with their surrounding context.
- Move through nested components without losing your place in the message.
Validate and highlight HL7 data
Use HL7 Soup as an online HL7 validator as well as an editor and viewer. Built-in structure knowledge and your own conformance rules help distinguish a message that merely parses from one the receiving interface can actually trust.
- Check required and empty fields, expected values, invalid dates, and data-table membership.
- Inspect validation details at segment, field, component, and sub-component level.
- Highlight important or invalid values across the editor, story, message list, and field grid.
- Reuse validation rules while reviewing vendor samples and regression-test messages.
Compare and anonymize messages
HL7 troubleshooting often moves from finding a difference to producing a safe example. The browser tool keeps those jobs in the same workspace.
- Compare two HL7 messages side by side and focus on meaningful field-level differences.
- Review changed values with the same field names and reference context used by the viewer.
- Anonymize identifying message content while preserving the structure needed for testing.
- Create safer samples for support, documentation, training, or vendor discussion.
Define HL7 interfaces and conformance rules
Turn a useful sample message, or a set of examples, into a shared definition of what another system should send or receive. Capturing requirements against the real HL7 structure makes the specification easier for analysts, testers, and vendors to understand and harder for it to drift away from the messages being tested.
Capture the contract
- Name and describe the interface in practical terms.
- Keep the expected message type and structure attached to the definition.
- Mark required fields, expected values, date checks, lookup tables, and highlighting rules.
Share and reuse it
- Import and export interface definitions so a team can use the same expectations.
- Apply the rules to vendor samples, release testing, and environment comparisons.
- Keep concrete conformance requirements close to the messages used to prove them.
Built-in practical HL7 reference guidance
HL7 Soup connects selected message fields to the Integration Soup HL7 Reference Guide. The guide is based on more than two decades of integration work and explains what fields mean, how tables and data types behave, and where real messages differ from tidy examples.
- Jump from a selected field to notes for its segment, field, data type, or table.
- Review field purpose, expected values, and practical interpretation without losing the message.
- Explore common laboratory, order/result, scheduling, document, and patient-administration structures.
