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
