Document Layout Handling & Extraction Behavior

Different document structures require specialized parsing logic to prevent broken rows and misaligned columns:

Document Layout Processing Method Expected Spreadsheet Output
Crisp High-DPI Screenshots (PNG / WEBP) Direct pixel coordinate boundary extraction 100% cell accuracy with preserved borders and headers
Smartphone Photos Taken at an Angle Planar perspective correction & deskewing Rectifies keystone distortion to align rows horizontally
Dark Mode or Inverted Screenshot Tables Automatic luminance inversion & contrast enhancement Inverts white-on-black pixels to optimize character recognition
Borderless Screenshots from Analytics Dashboards Whitespace gap histogram analysis Reconstructs column structure from numbers and labels

Common Conversion Challenges & Troubleshooting

1. Moire Lines and Scan Artifacts from Screen Photos

Cause: Taking a smartphone photo of a computer monitor produces wavy interference patterns that confuse OCR.
Solution: Take a direct screenshot (Windows: Win+Shift+S, Mac: Cmd+Shift+4) instead of photographing the monitor screen for crisp output.

2. Uneven Lighting or Glare Across Smartphone Photos

Cause: Shadows from your phone or overhead lights create uneven contrast across numbers.
Solution: Ensure the document is evenly illuminated under diffused ambient lighting, keeping your camera directly overhead.

3. Heavily Compressed JPEG Compression Artifacts

Cause: High JPEG compression creates blocky noise around small digits and decimal points.
Solution: Save screenshots in lossless PNG format when possible to preserve razor-sharp pixel edges for OCR.

Clear Data Privacy & Ephemeral Architecture

Stateless Processing: Uploaded over encrypted TLS 1.3 connections to our stateless conversion backend. Vector text coordinates are parsed via pdfplumber for digital PDFs, and character recognition is handled locally by Tesseract OCR and OpenCV for scans.

30-Minute Auto-Purge TTL: Documents are processed in isolated ephemeral storage and permanently deleted immediately upon export or after a 30-minute maximum TTL. We never store, inspect, or use your documents to train machine learning models.
