Use the free EDI Viewer as an online EDI reader that makes a dense X12 document easier to understand without changing the source file. Add one supported file or paste its text into the workspace above, and the Viewer identifies the transaction type before presenting information in a layout suited to that family. You can move between the structured representation and the Raw EDI view when you need to connect a readable value back to its segment context.
This free online EDI Viewer is designed for quick inspection: opening a remittance, reviewing a claim, checking an enrollment record, reading a purchase order, or understanding an acknowledgment before deciding what to do next. It supports the transactions listed below and runs without an account, daily Viewer quota, or Pro feature gate. For detailed field definitions beyond this focused viewing experience, use the linked EDI data mapping documentation.
The structured display is transaction-aware, so row meaning and available summary details vary by family. The Viewer does not force every X12 file into one generic table.
Open an 835 Electronic Remittance Advice to inspect payment and remittance information, claims, service details, patient responsibility, and adjustment data. The Raw view remains available for checking CLP, SVC, CAS, and related X12 segments. The display is a practical review aid, not a promise of complete payer-specific interpretation.
How to read an EDI 835Review Professional 837P, Institutional 837I, and Dental 837D claim files. Claim context is paired with the applicable service representation: SV1 for professional, SV2 for institutional, and SV3 for dental. You can also inspect the complete source-ordered Raw segment view.
Read the EDI 837 guideView benefit enrollment and maintenance information by member and coverage occurrence. The structured presentation helps connect enrollment actions, member identifiers, coverage details, and qualified dates while preserving a path back to the Raw X12.
How to read an EDI 834Inspect an eligibility inquiry by requester, payer, subscriber or dependent, trace context, dates, and requested service types. Each EQ occurrence remains associated with the patient inquiry it belongs to rather than being presented as an eligibility answer.
How to read an EDI 270Read an eligibility response with patient context, benefits, coverage information, service categories, and qualified details. Benefit occurrences and AAA rejection information are presented distinctly so a rejection is not mistaken for an ordinary benefit row.
How to read an EDI 271Inspect claim-acknowledgment status across receiver, provider, claim, and service levels. The Viewer keeps status context visible without implying that every row represents a claim or that an acknowledgment proves adjudication or payment.
How to read an EDI 277CARead an implementation acknowledgment from its functional group and transaction results down to reported segment and element issues. The hierarchy helps connect AK1, AK2, IK3, IK4, IK5, and AK9 information without inventing severity or treating implementation acceptance as business approval.
How to read an EDI 999Review purchase-order identity, dates, parties, PO1 lines, SLN sublines, products, schedules, prices, allowances, tax, and destination splits. The structured view uses one row per PO1 line plus each child SLN subline while Raw view preserves the physical segment order.
How to read an EDI 850Inspect purchase-order acknowledgment identity, BAK response context, PO1 lines, native ACK occurrences, schedules, products, parties, references, dates, contacts, notes, and source commercial evidence. The structured view keeps each ACK occurrence distinct and does not infer an overall business outcome.
How to read an EDI 855Inspect Ship Notice / Manifest identity, variable HL hierarchy, purchase-order context, parties, items, source quantities, packaging, carrier details, and MAN container identifiers. Malformed ancestry remains explicit instead of being guessed.
How to read an EDI 856Inspect warehouse shipping-order identity, ITEM and LX context, qualified products, parties, references, packing, routing, marks, and mechanism-separated source quantities. The view describes a directive or request and does not prove warehouse execution or fulfillment.
How to read an EDI 940Inspect source-reported warehouse shipping-advice identity, ITEM and LX context, ordered, shipped, and difference quantities, products, lots, parties, references, routing, marks, and W03 evidence without inferring delivery or fulfillment.
How to read an EDI 945Inspect transaction-set and functional-group acknowledgment status, nested AK3/AK4 error evidence, lexical AK9 counts, and provenance without inferring business outcomes.
How to read an EDI 997Inspect 131 string-safe fields for source-reported inventory evidence, physical LIN items, quantity qualifiers, destinations, schedules, parties, references, and CTT presence without inferring inventory accuracy or availability.
How to read an EDI 846Inspect 112 ordered string fields for source-reported product activity, with physical ZA rows and distinct product quantity, activity quantity, destination, and performance-condition collections. The view preserves qualifier-grounded evidence without treating it as verified sales, inventory, or demand.
How to read an EDI 852The Viewer reports the detected transaction type and provides a structured representation based on that transaction's useful review grain. An 835 focuses on claim payment information; an 837 presents claim and service context; enrollment, eligibility, and acknowledgment transactions use compact rows suited to their own occurrences. These projections are intentionally different because the underlying transactions answer different business questions.
The EDI View keeps source segments in order for Raw inspection. Use it to examine envelopes, transaction controls, loops, qualifiers, composites, and repeated elements alongside the structured display. Unsupported, malformed, or mixed-family input produces a bounded message instead of a fabricated transaction result.
The Viewer can download its current transaction-specific rows as CSV, an Excel XLSX workbook, or JSON. Export columns vary by transaction family because each structured projection preserves different business context. Raw-oriented 837 machine exports also retain their source-ordered segment and element shape.
Need XML output? Use the EDI Converter, which supports XML as part of its broader Smart Mapping, editing, and conversion workflow.
EDI file contents are processed by Viewer code in your browser. As part of supported browser-local Viewer processing, the application does not intentionally upload those contents to the application server. Normal page delivery still requires ordinary document, static-asset, and configured analytics requests, but those requests do not carry the EDI contents you paste or select. You remain responsible for using authorized files and following your organization's privacy and handling requirements.
Choose the tool that matches the task rather than treating every EDI workflow as the same operation.
An EDI viewer presents an X12 document in a form that is easier to read while preserving access to its Raw segments. It helps people inspect transaction content without manually decoding every delimited element.
The terms EDI viewer and EDI reader are often used similarly for tools that open and inspect EDI or X12 content. This Viewer is for reading and inspection; a converter changes output formats, a parser structures data, and a validator checks enabled rules.
The shared Viewer supports 835, 837P, 837I, 837D, 834, 270, 271, 277CA, 999, 850, 855, 810, 856, 940, 945, 997, 846, 852 transactions. Unsupported or mixed-family files receive a bounded message.
Yes. The Viewer distinguishes Professional, Institutional, and Dental 837 claims and presents their SV1, SV2, or SV3 service information where available.
Browser-local Viewer processing reduces the need to transmit EDI file content to the application server. The browser still makes requests needed to load the page, its static resources, and configured analytics.
Yes. You can export the current Viewer rows to CSV, Excel XLSX, or JSON. The available columns depend on the transaction family.
The Viewer is for quick reading and inspection. The Converter provides broader mapping, editing, conversion, and grouped download workflows.
The Viewer reports a bounded local message when content is malformed, unsupported, or mixes transaction families. It does not invent a structured result for content it cannot identify truthfully.
