PPTX to Text

Extract readable text from PowerPoint (.pptx) presentations using MinerU. MinerU outputs Markdown as the closest format to plain text.

Install

npm install -g mineru-open-api
# or via Go (macOS/Linux):
go install github.com/opendatalab/MinerU-Ecosystem/cli/mineru-open-api@latest

Quick Start

# Extract text from .pptx to stdout (no token required)
mineru-open-api flash-extract slides.pptx

# Save to file
mineru-open-api flash-extract slides.pptx -o ./out/

# Extract specific slides
mineru-open-api flash-extract slides.pptx --pages 1-5

# JSON output contains text fields per slide (requires token)
mineru-open-api extract slides.pptx -f json -o ./out/

Authentication

No token needed for flash-extract. Token required for extract:

mineru-open-api auth             # Interactive token setup
export MINERU_TOKEN="your-token" # Or via environment variable

Create token at: https://mineru.net/apiManage/token

Capabilities

• Supported input: .pptx (local file or URL)
• flash-extract: no token, Markdown output to stdout (max 10 MB / 20 pages)
• For truly plain text: use extract -f json and read text fields from JSON output
• Language hint with --language (default: ch, use en for English)
• Slide range with --pages (e.g. 1-5)

Notes

• MinerU has no -f text format; Markdown output is the closest to plain text
• For .ppt (legacy format), use ppt-extract instead
• Output goes to stdout by default; use -o to save to a file or directory
• All progress/status messages go to stderr; document content goes to stdout
• MinerU is open-source by OpenDataLab (Shanghai AI Lab): https://github.com/opendatalab/MinerU
