About the CSV/Excel Column Filter
The CSV/Excel Column Filter lets you keep only the columns you care about and drop the rest, producing a leaner file from a wide spreadsheet. When a dataset has dozens of columns but you need a handful, filtering trims it down in seconds.
Big exports often include far more fields than any one task needs, which makes them slow to scan and risky to share when some columns contain sensitive data. Selecting just the relevant columns produces a focused file that’s easier to work with and safer to hand off.
Filtering runs in your browser, so your data never leaves your device. That keeps the original dataset private while you pare it down, with no upload or account required.
How to use the CSV/Excel Column Filter
- Upload your CSV or Excel file.
- Review the list of detected columns.
- Select the columns you want to keep (or mark the ones to remove).
- Apply the filter to build the trimmed dataset.
- Download the resulting file with only your chosen columns.
Common use cases
- Trimming a wide export down to the few columns you actually need.
- Removing sensitive columns before sharing a dataset.
- Producing a focused file for import into another system.
- Simplifying a spreadsheet so it’s easier to read and analyze.
Frequently asked questions
Does filtering change my rows?
No. Filtering only removes columns; every row is preserved with just the fields you chose to keep.
Can I use it on both CSV and Excel?
Yes. The tool reads both formats, detects the columns, and lets you keep the ones you need.
Is the original file modified?
No. You download a new filtered file, and your original dataset is left intact.
Is my data uploaded to a server?
No. Filtering happens in your browser, so your data never leaves your device.
Can I also remove duplicate rows?
That’s a separate task — use the Duplicate Remover to eliminate duplicate rows after filtering columns.
