Data Security TLS 1.3 transfer, isolated memory execution, strict 30-minute auto-purge TTL

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
Bordered Tables with Grid Lines Lattice vector line intersection detection Reconstructs exact cell rectangles, line weights, and borders
Borderless Tables Defined by Whitespace Stream whitespace projection & gutter detection Identifies column gutters without requiring visible boundary lines
Merged Multi-Column Subheadings Colspan bounding box span calculation Preserves parent category headers spanning across child columns
Multi-Page Continuous Tables Repeating header signature matching Stitches rows across page breaks into a unified spreadsheet tab

Common Conversion Challenges & Troubleshooting

1. Missing Columns in Borderless Tables

Cause: Narrow whitespace gaps between adjacent numbers can sometimes cause column boundary detectors to merge them.
Solution: Select 'Accurate' mode, which applies strict vertical coordinate histogram analysis to detect subtle gutters.

2. Page Headers and Footers Captured as Table Rows

Cause: Running headers ('Quarterly Operations Report - Page 14') sharing page vertical alignment with table margins.
Solution: ConverCell applies margin filtering to exclude content above and below the primary data grid. Verify the preview table before exporting.

3. Split Multi-Line Row Content

Cause: Wrap-around text in narrow description columns breaking into separate spreadsheet rows.
Solution: Our proximity grouping engine aggregates lines with vertical separation < 1.4x line-height into the same row cell.

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.
