Why This Matters

Not all files convert to Excel with the same accuracy. Understanding the differences helps you:

• Choose the best source format when you have options
• Know what results to expect
• Troubleshoot when results aren't perfect

The Quick Answer

Native PDFs: The Gold Standard

What they are: PDFs created digitally — exported from accounting software, generated by websites, or saved from applications. The text is actual text data, not an image of text.

Why they convert best: The text is already digital. There's no image recognition involved. The system reads the exact characters that were typed.

What to expect: Near-perfect accuracy. Numbers, dates, and special characters all transfer correctly. The main challenge is complex table layouts, not text recognition.

Screenshots: Surprisingly Reliable

What they are: Screen captures from your computer or phone. Tables from websites, data from apps, or anything displayed on screen.

Why they work well: Screenshots have perfect image quality — no blur, no angle distortion, no lighting issues. The text is rendered crisply by your screen.

What to expect: High accuracy for standard fonts and clear table layouts. Unusual fonts or very small text may have occasional misreads.

Scanned PDFs: Depends on Scan Quality

What they are: Paper documents that were put through a scanner. The PDF contains an image, not selectable text.

The quality factor: A 300 DPI scan of a clean document converts excellently. A 100 DPI scan of a faded photocopy struggles.

What to expect: Good results with quality scans. Check the output for misread characters, especially with older or faded documents.

Phone Photos: Most Variable

What they are: Pictures taken with your phone camera of paper documents, receipts, whiteboards, or printed materials.

Why results vary: Lighting, angle, focus, and shadows all affect accuracy. A crisp photo in good lighting converts well. A blurry photo in dim lighting doesn't.

Tips for better photos:

• Use natural or bright artificial light
• Avoid shadows across the document
• Hold the camera directly above, not at an angle
• Make sure the entire table is in focus
• Use your phone's document scanning mode if available

Common Issues and Fixes

Numbers converted as text

If Excel treats numbers as text (left-aligned, can't sum them), highlight the column, go to Data → Text to Columns → Finish. Excel will convert them.

Misread characters

Common confusions: 0/O, 1/l/I, 5/S. Review critical numbers after conversion. Better source quality prevents most of these.

Columns not aligned

Tables without clear gridlines or with inconsistent spacing may have alignment issues. Source documents with visible borders convert more reliably.
