Extracted Table

No table data extracted. Upload a file and run extraction.

How to Use

1. Upload File

Upload a PDF or receipt/document image (JPG, PNG). Any format containing a table can be processed. Clearer images produce more accurate results.

2. Select OCR Language

Choose the language used in the document. Supports Korean, English, and Japanese. Use auto-detect for mixed-language documents. Accurate language selection improves recognition accuracy.

3. Run Extraction

Click "Extract Table" to start OCR. PDFs are first converted to images before text recognition. Real-time progress is displayed.

4. Edit and Export

Edit the extracted table directly in the preview. Click any cell to modify it, add or delete rows/columns. Download the final data as CSV or JSON, or copy it to the clipboard.

Use Cases

Receipt Expense Tracking

Photograph restaurant, grocery, or online shopping receipts to automatically extract items, quantities, and amounts into a table. Dramatically reduces time spent on expense reports.

Bank & Card Statement Analysis

Upload PDF bank statements or card bills to extract transaction data as CSV. Paste directly into Excel or accounting software for instant analysis.

Document Data Digitization

Digitize tabular data from paper documents — price lists, schedules, grade sheets, and more. Get automatically structured data without manual entry, greatly improving work efficiency.

Research & Academic Data Collection

Extract research data tables from academic papers or report PDFs for further analysis. Even tables embedded as images can be converted to text data via OCR.

Tips for Better Accuracy

  • Capture images at 300 DPI or higher resolution
  • Documents with clear table borders yield higher extraction accuracy
  • Digitally created PDFs produce better results than scanned copies
  • Use the edit feature to fix errors and fill in missing cells after extraction
  • Use auto-detect for documents with mixed languages
  • High-contrast black-and-white images have the best OCR recognition rates

FAQ

What file formats are supported?

PDF, JPG, and PNG formats are supported. PDFs are converted page-by-page to images before OCR processing. Both scanned and digitally created PDFs are supported, though digital PDFs yield higher accuracy. Maximum file size is 20MB.

How accurate is the OCR recognition?

Over 95% accuracy is achieved on clear printed documents. Handwriting or low-quality images may have lower recognition rates. Table structure detection works best when borders are clear and cells are well-defined. Errors can be corrected using the built-in edit feature.

Is my personal data safe?

All processing happens in your browser and no files are sent to any server. Receipts, statements, and other documents containing personal information are processed securely. Uploaded files and extracted data are deleted when you refresh the page.

Should I use CSV or JSON format?

CSV can be opened directly in Excel, Google Sheets, and other spreadsheet programs — ideal for data analysis and editing. JSON is suited for web developers or programmatic data processing. For general users, CSV is recommended.

What if the table is not extracted correctly?

Try improving image quality or changing the OCR language and run again. The extracted table supports direct editing — you can modify cell contents and add or delete rows and columns. Manual editing may be needed for complex or irregular table structures.

Can multi-page PDFs be processed?

The current version processes the first page of a PDF. For multi-page documents, split the PDF using a PDF splitter tool and process each page individually, or convert the PDF to images and upload each page in sequence.

Notice

  • Handle documents containing personal or confidential information carefully
  • Extraction results are for reference only; always verify important data against the original
  • Unauthorized use of data extracted from copyrighted documents may cause legal issues
  • Recognition accuracy varies by image quality, font type, and table format
  • Processing speed depends on file size and image complexity

Complete Guide to PDF & Receipt Table Extraction

Combines OCR (Optical Character Recognition) and PDF rendering to automatically extract table data from document images. Fully browser-based for complete privacy, with easy export to CSV and JSON formats.

Understanding Table Extraction Technology

OCR-based table extraction recognizes characters in images and analyzes position data to reconstruct row-and-column structures. The Tesseract OCR engine, developed by Google, supports over 100 languages and uses a deep learning-based LSTM neural network for high accuracy. PDF.js, developed by Mozilla, is a PDF rendering library that converts PDFs to images directly in the browser. Combining these technologies enables efficient extraction of tables from a wide variety of document formats.

Business Applications and Efficiency Gains

Table extraction technology plays a critical role in financial data automation, document digitization, and data migration. Expense management departments can process hundreds of receipts automatically, reducing data entry time by over 90%. Accounting teams can automatically structure bank statements and card records for direct import into accounting software. Researchers can easily extract data tables from papers for meta-analysis and secondary research.

Optimization for Maximum Accuracy

Image quality is the most important factor for the best extraction results. Recommended conditions include: scanned or photographed images at 300 DPI or higher, documents with clearly visible table borders, and strong contrast between background and text. Horizontally aligned images without skew and clean prints without smudging produce the best results. After extraction, use the edit feature to fix recognition errors and add rows or columns as needed to improve completeness.
