Envelope and control structure
Checks supported ISA/IEA, GS/GE, and ST/SE pairing, control values, and counts—for example, an SE segment count that differs from the parsed transaction.
EDI Validator
Validate supported X12 EDI files for structural and transaction-specific issues directly in your browser.
Up to 3 successfully processed files per day included. Failed, malformed, or unsupported attempts do not permanently consume the allowance. No account required.
Browser-local processing: EDI file parsing and validation run locally in the browser. EDI file contents are not uploaded to or stored by the application server.
Clear, reviewable validation results
Results identify severity, transaction family, safe field or segment context, and a concise explanation. These synthetic examples contain no real patient or business data.
Error837P

Warning835

How EDI validation works
An X12 validator begins by interpreting the file. Parsing turns raw X12 segments and elements into structured data; validation then checks that parsed content against the supported structure and rules enabled for the detected transaction. To inspect structured fields without leading with issue checks, use the EDI Parser.
- Choose a file. Select an authorized X12 EDI file inside the validator workspace.
- Detect and parse. The transaction type is identified and parsed locally in the browser.
- Run enabled checks. Structural and transaction-specific validation runs automatically after Smart Mapping.
- Review results. Errors and Warnings include safe transaction, segment, loop, row, or field context where available.
- Use the output. Inspect mapped data and export ordinary CSV, Excel, JSON, or XML under the existing product rules.
What the EDI Validator checks
EDI file validation combines enabled structural validation with transaction-specific validation. Coverage varies by transaction family and supported implementation version; each category describes implemented checks, not exhaustive implementation-guide coverage.
Required and situational data
Flags implemented requiredness and occurrence rules, such as a required transaction segment or element missing in its supported context.
Hierarchy and ownership
Reviews enabled loop, parent-child, and contextual ownership rules—for example, member, claim, service, or benefit information attached to the wrong supported scope.
Dates and numeric values
Checks supported date shapes and calendar values plus counts, amounts, quantities, ranges, and consistency—for example, an invalid date or malformed decimal.
Qualifiers and identifiers
Reviews implemented qualifier and code semantics plus selected identifier formats, such as an unknown supported code or invalid NPI where an XX qualifier applies.
Mapped output and acknowledgments
Checks selected mapped-output consistency and surfaces reported 999 or 277CA issues where applicable without treating recipient-reported content as certification.
Scope: A file can pass the enabled checks and still be rejected by a payer, clearinghouse, or trading partner because companion guides and business rules may add requirements. Validation does not guarantee recipient acceptance.
Common EDI validation issues
Common EDI validation errors include X12 syntax errors, required-content defects, invalid values, and contextual inconsistencies. These synthetic examples reflect issue classes the current validator can report; they contain no customer or patient data.
Controls and required content
Mismatched envelope controls, incorrect segment counts, missing required segments, or incomplete required elements can prevent dependable processing.
Dates, amounts, and quantities
Malformed dates, impossible calendar values, invalid decimals, inconsistent counts, or unsupported signed-value situations can produce targeted Errors or Warnings.
Codes, hierarchy, and scope
Unknown enabled codes, incorrect qualifiers, broken parent relationships, or data attached to the wrong claim, service, member, or benefit context can be reported.
Acknowledgments and mapped output
999/277CA reported errors, contradictory acknowledgment counts, duplicate output identities, and selected edited-output inconsistencies remain distinguishable for review.

Validate EDI without uploading file contents
EDI parsing, Smart Mapping, and enabled validation run in the browser, and EDI file contents are not uploaded to or stored by the application server.
Product network activity is separate from EDI content. Account, quota, privacy-safe analytics, and billing requests may use the network, but the application does not include EDI file contents in those requests.
Optional de-identification is bounded. It is off by default and applies to supported Smart Mapping fields and related presentation surfaces. Raw Mode preserves original source values and is not de-identified.
More than validation
After validation, use the same browser-local application to inspect and export the converted result.
Inspect and summarize
Review converted data and use Compact Summary for supported Smart Mapping results.
Export and de-identify
Export ordinary converted data as CSV, Excel, JSON, or XML and apply the available Smart Mapping de-identification option.
Expand with Pro
Use the full Data Editor, Full Analysis, saved layouts, and validation-report exports.
Pro adds unlimited product processing, full Data Editor/workspace access, Full Analysis, saved layouts, and validation-report exports. Pro is not required to run validation or view the free-safe validation details.
EDI validator FAQ
What does an EDI validator check?
An EDI validator checks parsed EDI content against enabled envelope, structural, formatting, consistency, and transaction-specific rules and reports issues for review.
Can I validate an EDI file without an account?
Yes. Guest access includes up to 3 successfully processed files per day without an account.
How many files can I validate?
Guest and Free users can successfully process up to 3 files per day across the product. Failed, malformed, or unsupported attempts do not permanently consume the allowance. Pro includes unlimited product processing.
Which X12 transactions are supported?
835, 837P, 837I, 837D, 834, 270, 271, 277CA, 999, 850, 855, 810, 856, 940, 945, 997, 846, 852 are supported within the current implementation and routing boundaries.
Does validation guarantee payer or trading-partner acceptance?
No. A payer, clearinghouse, trading partner, implementation guide, or companion guide may apply additional rules.
Is my EDI file uploaded to the server?
EDI file parsing and validation run locally in the browser. EDI file contents are not uploaded to or stored by the application server.
What is the difference between validation and parsing?
Parsing reads segments and elements so the application can map them. Validation applies enabled checks to the parsed source and mapped output.
Can I export validation results?
Detailed results can be viewed by Guest, Free, and Pro users. Validation-report CSV, Excel, and JSON export is a Pro feature; ordinary converted-data exports remain available under existing product rules.
