Why should I scale down the image for pixel export?

A 4000×3000 camera photo would produce 12 million spreadsheet rows — approximately 500MB of Excel data. Scale to 50×50 (2,500 rows) for a usable and shareable file.

How accurate is the OCR table extraction?

Accuracy depends on image quality. For clear, well-lit, printed tables with standard fonts, accuracy is typically 85–95%. Handwritten text, unusual fonts, or poor lighting reduce accuracy significantly.

Utilities

Convert Images to Spreadsheet Data

The Image to Spreadsheet tool serves two distinct use cases: pixel-data export and table extraction. In pixel mode, it samples each pixel's color and writes it to a spreadsheet grid — useful for color analysis, pixel art workflows, or creating colored Excel pixel art. In OCR mode, it uses Tesseract.js to recognize text in a photo of a spreadsheet or table and reconstructs the data as a downloadable CSV, Excel, or Markdown table.
