The problem
How it works
PP-StructureV3 combines layout detection, OCR and optional table, formula, chart and seal recognition, plus multi-column reading order recovery. You run it with `paddleocr pp_structurev3 -i <file>` or the Python `PPStructureV3().predict()` call, then save results as JSON, Markdown with extracted images, or Word; multi-page PDFs can be merged into one Markdown file.
Results and limitations
The README says PaddleOCR turns PDFs and images into structured, LLM-ready JSON or Markdown for RAG and agent use, with support for many languages.
Before you try it
PaddlePaddle must be installed separately, the default models are large and can be slow on CPU, and the docs recommend a GPU or lighter models. Results depend on your setup and were not independently reproduced by Top 200 Repos.
Tools and repositories
- Tools
- Python · PaddlePaddle · paddleocr CLI · NVIDIA GPU (recommended)
- Prerequisites
- No API key for local runs; a GPU is strongly recommended for the default models.
Try it yourself: Extract structure from scanned files
Fill the fields to adapt the prompt. Empty fields stay as visible [placeholders].
Use PaddleOCR PP-StructureV3 to parse the files in [Input folder], which are mostly [Document kind] in [Language]. Check whether PaddlePaddle and a GPU are available and show me the install commands before running them. Process one sample file first, save JSON and Markdown to [Output folder], and show me the Markdown so I can judge table and reading-order quality before you run the full batch. For PDFs, merge pages into one Markdown file per document. Report per file: pages processed, tables found, and any page that failed or produced little text.Validate extracted numbers against the original scan before using them in finance or legal work.
