Bin Column in Excel Files Online
Bucket a numeric column in Excel files into labelled ranges — equal-width bins or custom edges. Runs entirely in your browser.
How to bin Column in Excel files
- Drop your file. The first numeric column is preselected, and the new column name defaults to its name plus _bin.
- Pick the column to bin. Only numeric columns are listed.
- Choose Equal-width bins and set how many (2 to 50, default 5), or choose Custom edges and type the break points separated by commas, without thousands separators.
- Choose Add as new column or Replace column, then click Bin column.
- Check the labels in the preview and download the file in the same format.

Worked example
A food delivery service wants to report how many orders arrived within 30 minutes, within an hour, within two hours, and later than that.
Input (Excel)
Excel workbook, first sheet (Sheet1)
| order_ref | zone | delivery_minutes |
|---|---|---|
| D-8812 | Northside | 22 |
| D-8813 | Harbour | 45 |
| D-8814 | Northside | 60 |
| D-8815 | Airport | 135 |
| D-8816 | Harbour | 30 |
Settings
- Column to bin: delivery_minutes
- Binning mode: Custom edges
- Edge values: 0, 30, 60, 120
- New column name: delivery_minutes_bin
- Output: Add as new column
Result
| order_ref | zone | delivery_minutes | delivery_minutes_bin |
|---|---|---|---|
| D-8812 | Northside | 22 | < 30 |
| D-8813 | Harbour | 45 | 30 – 60 |
| D-8814 | Northside | 60 | 60 – 120 |
| D-8815 | Airport | 135 | ≥ 120 |
| D-8816 | Harbour | 30 | 30 – 60 |
Each range includes its lower edge and excludes its upper edge, so 30 falls in "30 – 60" and 60 in "60 – 120". Everything below the second edge is labelled "< 30", and the first edge, 0, does not appear in any label. Values at or above the last edge share "≥ 120". The labels are text, ready for Count by value.
Working with Excel files
Only columns that load as numbers can be binned, and the loader reads each cell on the first sheet as the text it displays. Cells formatted as currency, as percentages or with thousands separators arrive as text and are not listed. A cell showing 45% is the text "45%" here, not the number 0.45. Set those cells to General or Number format in Excel and save, or strip the symbols with Find and Replace and then cast the column to a number.
The result is a new workbook with one sheet, and the labels are plain text cells. A PivotTable or COUNTIF can group on them straight away. A PivotTable sorts text labels alphabetically, though, so "100 – 200" comes before "30 – 60". Drag the items into order once, or sort on the original number column, which Add as new column keeps next to the labels.
Frequently Asked Questions
Why is my Excel percentage column not listed?
The loader reads the displayed text, so 45% arrives as text rather than a number. Format the column as General or Number in Excel and save, then load the file again.
Can I use the bin labels in an Excel PivotTable?
Yes. They are plain text cells. Put the label column in Rows and any column in Values to count or sum by range. Reorder the rows by hand, because text sorting does not follow numeric order.
Why does equal-width binning give me one more label than the number of bins?
The last edge is the column maximum, and values at or above the last edge get their own "≥" label. With 5 bins on values from 0 to 100 the labels are < 20, 20 – 40, 40 – 60, 60 – 80, 80 – 100 and ≥ 100, and only the maximum lands in the last one. For exactly N groups, use custom edges and put the last edge above the maximum.
What happens to empty values?
They stay empty. A NULL number gets a NULL label, so it is not counted in any range. Use Fill Nulls first if you want them in a range of their own.
How do I sort the bin labels in the right order?
The labels are text, so a plain sort puts "100 – 200" before "30 – 60". Sort by the original numeric column instead. Choosing Add as new column keeps that column in the file.
