HWP Editor

This tool provides browser-based editing and conversion for Hangul Word Processor (HWP) documents, enabling users to work with HWP files without native software. Primary users include students, researchers, HR and legal teams, translators, and Korean-language teams who routinely receive HWP documents and require quick edits, formatting adjustments, and reliable cross-format exports. It is designed for scenarios where local HWP installations are unavailable or collaboration relies on a centralized workflow. The editor preserves core document structures—such as headings, lists, tables, and embedded objects—and aims to maintain fidelity during export across formats and platforms.
It builds on a structured in-browser document model derived from the HWP format. The parser ingests an HWP file, constructs a stable document tree, and exposes operations that modify text, styles, and layout in a format-preserving manner. Exports are supported to PDF, DOCX, HWPX, and back to HWP, with font mapping to common Korean fonts, basic image handling, and table editing. Optional features include metadata management, batch export, and controlled font substitution to minimize layout drift. The approach emphasizes reliability, traceability of edits, and predictable cross-format results.
Inputs include: file_input (type=file, required; sample sample.hwp; validation: MIME or extension HWP, max size 20MB) and settings such as operation (string, optional; default 'edit') and preserve_formatting (boolean, optional). Outputs include output_file (type=file; format depends on export), status (string), download_url (string), and a concise validation/report (string). The tool communicates results in a structured manner suitable for automation and auditing.
Algorithms, Error Handling & Localization: Algorithms rely on a format-aware parser to build an in-memory document tree, apply edits by mutating nodes, and reserialize to the target format with conservative fallbacks. Error handling detects corrupted inputs, unsupported features, missing fonts, or export failures, providing diagnostics while preserving the original source. Industry localization notes cover Korean language support and Unicode handling, with adherence to regional document standards. Assumptions & Exclusions: designed for single-user editing; not real-time collaboration; advanced typography, script-specific features, or multi-user workflows may require desktop tools or extended pipelines.
