# Guides for document-to-text pipelines.

Practical write-ups on extracting, OCR-ing, and parsing documents for RAG, search, and LLM ingestion. No fluff, just how to do it.

-   **[Getting text out of video and audio: extraction vs. transcription](https://txtfetch.com/blog/text-from-video-and-audio)**
    Aug 15, 2026 — Text in a media file can live in a sidecar, an embedded track, a container tag, or nowhere at all. Extraction and speech-to-text are different jobs.

-   **[Per-document vs per-page pricing for document extraction](https://txtfetch.com/blog/per-document-vs-per-page-pricing)**
    Jul 14, 2026 — Per-page pricing looks cheaper until you multiply it by a 300-page report. This post frames what actually predicts your bill, and when per-page wins.

-   **[Ingesting large documents and big batches without falling over](https://txtfetch.com/blog/batch-and-large-document-ingestion)**
    Jun 23, 2026 — A 500-page PDF and a ten-thousand-file backfill stress the same two things: single-request time and concurrency.

-   **[Extracting tables from PDFs and spreadsheets for RAG](https://txtfetch.com/blog/extract-tables-for-rag)**
    Jun 2, 2026 — Tables don't survive naive text extraction. They collapse into number-soup with no row or column structure. Structure-aware extraction keeps them usable.

-   **[Using txtfetch as a LangChain and LlamaIndex document loader](https://txtfetch.com/blog/langchain-llamaindex-document-loader)**
    May 5, 2026 — There's no official txtfetch SDK yet. Wiring the endpoint into a LangChain or LlamaIndex loader takes about fifteen lines.

-   **[Chunking strategies for RAG: from clean text to good retrieval](https://txtfetch.com/blog/chunking-strategies-for-rag)**
    Apr 7, 2026 — Fixed-size, recursive, and structure-aware chunking all assume clean extracted text. Extraction quality bounds chunk quality, whichever one you pick.

-   **[Parsing DOCX, PPTX, and XLSX into clean text for LLM ingestion](https://txtfetch.com/blog/parse-office-docs-docx-pptx-xlsx-for-llms)**
    Mar 10, 2026 — python-docx, python-pptx, and openpyxl each have their own API and their own way of failing on real files. One endpoint replaces all three.

-   **[OCR scanned documents and images through one API call](https://txtfetch.com/blog/ocr-scanned-documents-api)**
    Feb 3, 2026 — Scanned invoices, faxed contracts, and photographed receipts have no text layer, so they OCR through the same endpoint as everything else.

-   **[How to extract text from a PDF for RAG (without maintaining a parser)](https://txtfetch.com/blog/extract-text-from-pdf-for-rag)**
    Jan 12, 2026 — Feeding PDFs into a RAG pipeline breaks the usual parser stack: multi-column layouts, embedded tables, scanned pages. One request handles all three.
