## What it is
Omniparser is a native Go ETL library that streams input data in formats like CSV, JSON, XML, fixed-length text, and EDI/X12/EDIFACT, transforming it into JSON output via JSON-declared schemas. It supports XPath-based record filtering, custom transform functions including JavaScript, and custom file formats.

## Use cases
- parse large CSV files into JSON in streaming fashion
- convert EDI X12 or EDIFACT documents to JSON
- transform XML feeds with XPath-based extraction
- parse fixed-width text files with a schema
- ingest and transform JSON data pipelines in Go
- define codeless data transformations with JavaScript custom functions

## When to choose
- you need a schema-driven, streaming parser for multiple flat/hierarchical formats in Go
- you process EDI X12/EDIFACT or fixed-length files
- you want declarative transforms without writing bespoke parsing code

## When to avoid
- you need a full distributed ETL platform rather than an in-process library
- your project is not in Go
- you need binary formats like Parquet or Avro

## Facets
- artifact type: library
- maturity: active
- function: parser, etl, serialization, streaming
- domain: files, developer-tools
- platform: go, cross-platform
- tags: csv, xml, edi, x12, edifact, fixed-length, schema-driven, javascript-transforms, data-transformation, data-engineering
