## Overview
Parse, inspect, and translate EDI X12 and UN/EDIFACT documents into clean, human-readable hierarchical trees and structured JSON. Designed for supply chain, logistics, and healthcare integration specialists.

## Format Specifications
- **Category:** Security & Dev
- **Supported Formats:** `X12`, `EDIFACT`, `JSON`, `XML`, `EDI`
- **Privacy Guarantee:** 0 bytes uploaded to remote servers. All computation executes locally in browser memory.
- **Compliance:** GDPR, HIPAA & SOC 2 Friendly (process sensitive payloads and PII directly on your local device).

## Technology Stack
- Custom EDI Lexer & Tokenizer
- Hierarchical Tree Generator
- Interactive Data Grid
- JSON Serializer

## How It Works
1. EDI documents are tokenized based on segment terminators (~, \n) and element delimiters (*, +).
2. Interchanges (ISA/UNB), Functional Groups (GS/UNG), and Transaction Sets (ST/UNH) are reconstructed into an interactive hierarchy.
3. Segments and elements are cross-referenced with known standard definitions for instant identification.
4. The parsed transaction tree converts seamlessly to JSON for programmatic ingestion.

## Practical Use Cases
### Healthcare Claims & Eligibility Review
Inspect confidential EDI 837 claims and 834 benefit enrollment files without violating HIPAA data upload guidelines.

### Supply Chain & Retail Order Processing
Troubleshoot EDI 850 Purchase Orders, 856 Advanced Shipping Notices (ASN), and 810 Invoices locally during vendor onboarding.

### Logistics & Freight EDIFACT Inspections
Parse ORDERS, DESADV, and INVOIC EDIFACT transmissions for maritime and international freight integrations.

### Modern API Migration
Convert raw legacy EDI files into structured JSON objects for modern cloud event architectures and serverless functions.

## Frequently Asked Questions
### Is it safe to view confidential patient or commercial EDI files here?
Yes. Unlike cloud EDI translation services that ingest your files, Privatools executes the entire lexical analysis and JSON generation on your machine. Zero bytes leave your browser.

### Which EDI standards are supported?
It supports ANSI ASC X12 (including EDI 850, 855, 856, 810, 837, 834, 997) and UN/EDIFACT (ORDERS, DESADV, INVOIC, etc.).

### Can I export the parsed EDI structure as JSON or CSV?
Yes. You can copy or download the normalized JSON schema representation directly to your clipboard or local disk.
