OCR Numbers to Excel Automation

I have a growing batch of camera-taken JPEGs, each showing only a few numeric readings that I need recorded. Manually copying those figures into Excel is becoming unmanageable, so I need a small program that can do three things in one pass:

1. Load every JPEG in a chosen folder.
2. Detect and read the numbers shown in each image (OCR—Tesseract or a comparable engine is fine).
3. Append those numbers, in order, to a specific worksheet/column layout that I will supply.

The workflow should be fully automated: point the script or executable at a folder, hit run, and receive an updated .xlsx file. No cloud calls—everything must run locally on Windows 10.

Acceptance will be based on:
• At least 95 % accuracy across a test set of 100 images.
• Clean Excel output with no mixed or stray characters.
• Clear setup instructions so I can reproduce the results on a second PC.

If you prefer Python (OpenCV + pytesseract) or another language that ships easily, that works for me as long as dependencies are listed and installation is straightforward. (MAC AND PC)
