Build advanced search index mappings. Convert text elements into structural JSON files mapping character streams directly to coordinate planes.
Built for confidential workflows — files stay in your browser memory.
Stop guessing text coordinates in PDF layout analysis. Extracting spatial coordinates is easy with our developer positioning parser. It scans page vectors, maps font styles, and exports character coordinates in clean JSON formats seamlessly. By utilizing a local OCR character parser, this developer API script maps word positions, visual layout frames, and reading streams, making it easy to code custom text extractors. The entire process runs client-side inside WebAssembly, keeping your raw files private and secure in your programming pipeline.
Select the file containing the layout coordinates you want to map.
The script scans character streams and registers spatial coordinates.
Save the layout coordinates directly as a structured JSON file.
| Feature Metric | Traditional Cloud Services | GoLocalPDF Sandbox |
|---|---|---|
| Coordinate Accuracy | ❌ Strips margins, returning plain text blocks | ✅ Maps bounding boxes to exact page coordinates |
| Integration Options | ❌ Locked behind proprietary SDK API formats | ✅ Structured, developer-ready JSON exports |
| Data Control | ❌ Transmits layout files to remote cloud services | 🛡️ Safe browser sandbox. No file uploads |
| Speed & Scale | ❌ Heavy queues on third-party conversion hosts | ⚡ Instant local processing in browser memory |
It maps word positions, visual layout frames, and reading streams, making it easy for developers to build custom programming extractors and parse JSON data maps.
It outputs coordinates in standard PDF points scale, mapping layouts to match the original document page size for developer OCR parsing pipelines.
Yes, everything runs in your local browser sandbox WebAssembly thread. Your programming files and code data are never uploaded to external servers.
