Lightweight RTF Text-Draft Extractor
Extract main-body text using RTF groups, font codepages and Unicode escapes. Contiguous hexadecimal bytes are decoded together, including Chinese, Japanese and Korean. Paragraphs, line breaks and table rows become newlines; tabs and table cells become tabs. Spaces and the final newline are preserved. Files retain their original bytes; pasted non-ASCII characters are treated as Unicode.
About this lightweight rtf text-draft extractor
Extract main-body text using RTF groups, font codepages and Unicode escapes. Contiguous hexadecimal bytes are decoded together, including Chinese, Japanese and Korean. Paragraphs, line breaks and table rows become newlines; tabs and table cells become tabs. Spaces and the final newline are preserved. Files retain their original bytes; pasted non-ASCII characters are treated as Unicode Parses and structures office document payloads locally in memory without transmitting private company files to external servers.
Document parsing & data extraction pipeline
Inspects, parses, and converts open publishing and scheduling formats conforming to IDPF EPUB 3.2 / 3.3 specifications, IETF RFC 5545 (iCalendar - .ics), and RFC 6350 (vCard v4.0 - .vcf). EPUB tools unpack the OCF (Open Container Format) ZIP package, parsing META-INF/container.xml and the OPF (Open Packaging Format) package document to extract Dublin Core metadata (dc:title, dc:creator, dc:identifier), spine order, manifest items, and table of contents (NCX / Nav doc), converting chapters to Markdown.
Worked document extraction example

File size & structure constraints
Input must be smaller than 10,000,000 bytes (pasted text measured as UTF-8). Limits: 256 nested groups, 4,096 font definitions, 1,000,000 control/group tokens, 10,000,000 UTF-16 output units and 30 seconds including reading. Preview pages show 16,000 UTF-16 units; downloads contain the complete text. Codepages: Windows 874, 932, 936, 949, 950, 1250–1258, 866, Mac Roman 10000, Mac Cyrillic 10007 and UTF-8 65001, using browser TextDecoder mappings. Unsupported codepages, invalid encoded bytes and lone Unicode surrogates produce errors. Font/color/style tables, pictures, objects, headers, footers, footnotes, comments, hidden/deleted text, field instructions and ignorable destinations are omitted; stored field results are retained. No field execution, OCR, font-specific symbol glyphs, layout reconstruction or complete RTF conformance certification.
