Delete the Nth paragraph (0-based) from an .hwpx body. Args: file_path, index, output_path (optional).

Delete the Mth column (0-based) from the Nth table in an .hwpx (removes one hp:tc from every row). Args: file_path, table_index, col_index, output_path (optional).

Delete the Mth row (0-based) from the Nth table (0-based) in an .hwpx. Args: file_path, table_index, row_index, output_path (optional).

Save every embedded image to disk. Args: file_path, output_dir (optional; defaults to _images/).

Fill multiple placeholders in an HWPX template. replacements is a JSON object string, e.g. {"{{name}}":"Kim","{{company}}":"Acme"}. v0.2: .hwpx only. Args: file_path, replacements, output_path (optional).

Get a Hancom field's current value by name. Args: file_path, name.

Get document metadata (version, page count, section count, fonts used, totals for tables/images/footnotes/equations/headers/footers). Args: file_path.

Get per-section page definition (paper size, margins, columns) and section properties. Useful for understanding document layout. Args: file_path.

Insert a new image into an .hwpx — adds the file to BinData/, registers it in content.hpf, and appends a paragraph with an inline hp:pic. Args: file_path, source_path, ext (png/jpg/bmp/gif; auto from source_path if omitted), output_path (optional).

Insert a real OWPML table at the end of an .hwpx body (proper hp:tbl/hp:tr/hp:tc). headers and rows are both JSON string arrays — headers is a single-row array of strings, rows is an array of row arrays. Args: file_path, headers, rows, output_path (optional).

List ZIP entries under BinData/ inside an .hwpx (image and binary attachments). Useful before replace_hwp_image. Args: file_path.

List Hancom-style fields (<hp:fldBegin>/end pairs) in the document, with name and type when available. Useful before fill_hwp_template. Args: file_path.

List embedded images (mime, byte length, locator) in an HWP/HWPX file. Args: file_path.

Merge horizontal cells in a row of a table by setting colSpan on the first cell and removing the absorbed cells. Args: file_path, table_index, row, col_start, col_count (>=2), output_path (optional).

Merge vertical cells across rows in a single column by setting rowSpan on the first cell and removing absorbed cells in following rows. Args: file_path, table_index, col, row_start, row_count (>=2), output_path (optional).

Read full HWP/HWPX document content as text + tables (markdown) + image listing. Args: file_path (absolute path).

Extract every table from an HWP/HWPX file as GitHub-flavored markdown. Args: file_path.

Extract plain body text from an HWP/HWPX file (no tables, no images). Args: file_path.

Render every page of an HWP/HWPX as SVG files in a directory. Args: file_path, output_dir (default _pages/), max_pages (optional limit).

Render an OWPML equation script (e.g. 'TIMES LEFT ( {a} over {b} RIGHT )') to SVG. Args: script, font_size (HWP units, default 1300), color (default 0).

Render a single page of an HWP/HWPX as HTML. Useful for AI consumption when SVG isn't ideal. Args: file_path, page (0-based, default 0), output_path (optional).

Render a single page of an HWP/HWPX document as SVG. If output_path is omitted, the raw SVG string is returned inline (useful for direct LLM consumption). Args: file_path, page (0-based, default 0), output_path (optional).

Replace an embedded image inside an .hwpx by overwriting its BinData/ ZIP entry with new file contents. target accepts either basename ('image1.bmp') or full entry path ('BinData/image1.bmp'). Args: file_path, target, source_path, output_path (optional).

Find and replace text in an HWPX file. v0.2: only .hwpx is supported as input/output. Args: file_path, old_text, new_text, output_path (optional).

Replace a single cell's text in a table inside an .hwpx. Args: file_path, table_index, row, col (all 0-based), text, output_path (optional).

Set a Hancom field's value by name in an .hwpx (writes the new text between the matching <hp:fldBegin name=...> and <hp:fldEnd>). Use list_hwp_fields first to discover names. Args: file_path, name, value, output_path (optional).

Replace the entire text of the Nth paragraph (0-based) in an .hwpx body with new text. The paragraph attributes (paraPr/style refs) are preserved; runs are collapsed into a single hp:run with the new text. Args: file_path, index, text, output_path (optional).
