| Data Privacy & Retention | TLS 1.3 encrypted transfer, isolated temporary memory, automatic 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 |
|---|---|---|
| Cells with Embedded Commas | RFC 4180 double-quote encapsulation | Preserves internal punctuation without creating phantom CSV columns |
| Multi-Line Text in Table Cells | Quoted multiline string wrapping | Loads seamlessly into Pandas and SQL without line truncation |
| Empty / Missing Data Cells | Consecutive delimiter insertion (,,) | Maintains strict column indexing across all rows |
| Currency Symbols & Percentages | Header type detection & optional numeric casting | Numeric figures ready for mathematical aggregation in code |
Common Conversion Challenges & Troubleshooting
1. Commas Inside Address or Description Columns
Cause: Unescaped commas in street addresses (e.g., '123 Main St, Suite 400') can split a single cell into two separate CSV columns.
Solution: ConverCell automatically wraps cells containing commas in standard RFC 4180 double quotes. When importing into Python, use pandas.read_csv(filepath, quotechar='"').
2. Special Characters or Currency Symbols Corrupted
Cause: Opening CSV files in older spreadsheet viewers with ANSI or ISO-8859 encoding can scramble UTF-8 symbols.
Solution: All CSV exports from ConverCell are encoded in standard UTF-8. In Excel, import via 'Data > From Text/CSV' and select UTF-8 as the file origin.
3. Trailing Blank Rows in CSV Output
Cause: Document page footers or signature spaces can sometimes be read as empty rows.
Solution: ConverCell trims trailing whitespace. In Python, run df.dropna(how='all') to instantly discard any unwanted empty spacer rows.

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.
