Excel to Scatter Plot

Upload your .xlsx, choose the X and Y numeric columns, and Plotiq renders a scatter plot with an optional least-squares regression line. No install, no signup.

Ideal for correlation analysis, lab measurements, and quick data-quality checks.

1. Upload your .xlsx

Drag the workbook in. First non-empty sheet loads automatically.

2. Pick numeric X and Y

Choose one numeric X column and one or more numeric Y columns.

3. Toggle the regression line

Optionally overlay a least-squares regression line with R² label, then export.

Does it draw a best-fit line?

Yes — toggle the regression overlay to add a least-squares fit line with R² label.

Can I plot multiple Y series on the same scatter?

Yes. Each Y column becomes its own color-coded point series.

Is my Excel file uploaded?

No. Parsing and rendering happen in your browser — the workbook never leaves your device.

What about log-scale axes?

Yes. The Y axis can be switched to log10 for data spanning multiple orders of magnitude.

Maximum size?

10 MB / 5,000 rows. Well above what a scatter plot renders smoothly.
