    Extracted table

    Your image is processed locally in this browser tab using Tesseract.js (WebAssembly OCR). It is never uploaded to Calcooo or any server — only the OCR engine and language data are fetched from a CDN.

    Note: table reconstruction is a best-effort heuristic based on word positions, not a true table-structure parser. It works well on simple grid-like tables with clear row and column alignment, and less well on complex tables with merged cells.

    How to use this tool

    1. Drag and drop a photo or screenshot of a table into the box above, or click to browse and select one.
    2. Choose the language that matches the text in your table.
    3. Press Extract table and wait a moment while OCR runs and the table is reconstructed.
    4. Check the preview table, then download the result as a CSV file.

    FAQ

    Frequently asked questions

    Is my image uploaded anywhere?

    No. Everything runs entirely on your device using Tesseract.js, an open-source OCR engine compiled to WebAssembly. Your image is never uploaded to Calcooo or any server.

    How accurate is the table structure?

    This is a best-effort reconstruction based on the horizontal and vertical position of recognized words. It works well on simple, clearly-aligned tables with consistent spacing, but may misalign columns on tables with merged cells, rotated text, or very tight spacing.

    What format do I get?

    A CSV file you can open directly in Excel, Google Sheets, or any spreadsheet app, plus a live preview table on this page so you can check the result before downloading.

    Can I fix mistakes before downloading?

    Not directly on this page — download the CSV and correct any misaligned cells in your spreadsheet app, or retake the photo straighter and with more even lighting for a better result.
