Image to CSV Table Converter — Free and Browser-Based

An image-to-CSV table converter turns a picture of a table — screenshot, scan, or phone photo — into structured comma-separated data you can paste into Excel, Google Sheets, or any database. The conversion uses OCR (optical character recognition) to read text, plus geometric analysis to determine which text belongs in which row and column. Here's which image types work best, what to expect in terms of accuracy, and the three settings that change the output the most.

What image types the tool accepts

Format	Works well?	Notes
PNG (screenshot)	Excellent	Ideal — lossless, native resolution
JPG (photo)	Good	Keep quality 85+ to avoid compression artifacts on text
WebP	Excellent	Same as PNG for lossless; quality 90+ for lossy
BMP	Excellent	Uncompressed — works perfectly, but files are huge
HEIC (iPhone)	Works via auto-convert	Browser converts to PNG first; no manual step needed
GIF	Limited	Only first frame read; 256-color palette affects accuracy
TIFF	Not directly	Convert to PNG first
PDF	No	Use our PDF table extractor instead

The three-click flow

1. Drop the image onto the upload zone, or paste from clipboard with Ctrl+V / Cmd+V.
2. Click Extract Table. Processing typically takes 2-5 seconds for a single-page table; longer for complex or high-resolution images.
3. Review the preview. Click Download CSV or Copy CSV.

That's it. No account, no upload queue, no usage quota.

Three factors that change accuracy the most

1. Image resolution. A 1200-pixel-wide table image extracts cleaner than the same table at 600 pixels. For photos, shoot at 300+ DPI. For screenshots, use native resolution (2x/3x on Retina/high-DPI screens).
2. Font style. Sans-serif fonts (Arial, Helvetica, Inter) OCR better than serif (Times, Georgia). Decorative or condensed fonts drop accuracy further. If you control the source, pick sans-serif when possible.
3. Row spacing. Tightly-packed rows sometimes merge during column detection. A bit of vertical whitespace between rows helps. If the source is crammed, try zooming the browser to 150-200% before screenshotting.

What OCR cannot handle cleanly

• Heavily stylized data viz. Infographics with overlapping shapes, gradient backgrounds, and decorative numbers aren't tables — they're art. OCR can't extract the underlying data.
• Rotated or skewed images. Phone photos of printed tables at an angle. Deskew the image first in any photo editor.
• Watermarked tables. A watermark that crosses rows breaks column alignment. Increase contrast or crop the watermark out before extraction.
• Tables with images inside cells. Product photo tables, icon-based comparison charts. The image cells extract as blanks (which is probably what you want anyway).
• Small text (under 10px). Below a certain pixel height, OCR can't distinguish characters reliably. Zoom the source, re-screenshot.

After export — CSV best practices

A few post-export steps that almost always save time:

• Open in Excel with UTF-8 encoding. Our CSV is UTF-8; Excel's default CSV import is ASCII on older Windows versions. Use Data → From Text/CSV and pick UTF-8 explicitly to preserve currency symbols and special characters.
• Convert numeric columns. OCR returns all text. After import, highlight numeric columns in Excel and set the format to Number or Currency.
• Review header row alignment. The first CSV row should be your headers. If the extractor split a merged header into multiple rows, delete extras in Excel.
• Paste into Sheets for structured import. Google Sheets' CSV paste is more forgiving than Excel's — it infers types per column automatically.

If you then need to convert the CSV to Excel .xlsx, our CSV to Excel tool does that in one step.

Frequently Asked Questions

What image formats does the table extractor accept?

PNG, JPG, WebP, and BMP work directly. HEIC from iPhone auto-converts through the browser. TIFF requires conversion to PNG first. PDF is not supported — use our dedicated PDF table extractor for that.

How accurate is image-to-CSV conversion?

For clean screenshots with sans-serif fonts at 1080p+, expect 95%+ character accuracy. Phone photos of printed tables drop to 85-90%. Handwritten tables drop further, often below usable. Always spot-check numeric columns.

Can I extract tables from an iPhone photo?

Yes. HEIC photos from iPhone work directly — the browser auto-converts to PNG internally. For best results, shoot the photo straight-on (not at an angle) with good lighting and no shadows across the text.

Does this work for multi-page tables?

The tool processes one image at a time. For a table that spans multiple pages, take one screenshot per page and run each through separately, then concatenate the CSVs in Excel. For PDF documents with multi-page tables, use our PDF-to-Excel tool instead — it handles pagination automatically.
