Image Table to Excel OCR
Image table to Excel/CSV via client-side Korean tesseract.js OCR.
About this tool
Image Table to Excel OCR (imgocr) extracts tables from images β PDF screenshots, scanned receipts / contracts, generic screenshots β using Tesseract.js WASM (Korean + English) and exports them as XLSX, CSV, or JSON. All OCR runs in the browser; no images are uploaded (verifiable via DevTools Network). The detected table is editable cell-by-cell. Accuracy is 90β97% on clean scans / screenshots. Supports drag-and-drop, multi-image batch processing, and Korean / English simultaneous recognition. Useful in accounting, HR, research, and journalism whenever you face paper or image tables.
Use cases
Scenario 1
PDF table β Excel
When a protected PDF blocks copy-paste, finance captures the page and converts it straight to Excel for analysis.
Scenario 2
Scanned receipts / contracts
Finance scans a stack of business-trip receipts, OCRs date / amount / vendor, and bulk-loads them into the accounting system.
Scenario 3
Academic / research data
A researcher extracts a statistical table screenshot from a paper PDF and converts it into CSV ready for R or Python analysis.
Scenario 4
Strict security environment
In environments where cloud OCR APIs are forbidden, digitize tables entirely on the client without any external transmission.
