Check OCR numbers before using Excel formulas

Why this happens

Recognition can confuse similar characters such as O and 0, or miss decimal marks and minus signs. A valid-looking cell can still contain the wrong value.

What to try first

Compare high-impact cells to the PNG, correct the data, and only then calculate totals. Keep the source image alongside the workbook for reference.

Try it on a fresh copy

1. Choose a sharp PNG screenshot and crop away unrelated content first.
2. Run recognition and download the Excel workbook.
3. Compare important values with the screenshot. Fix row alignment and misread digits before calculating totals.

How to tell whether it worked

Verify every important number and confirm that values land in the correct rows and columns.
