What is this CSV column selector?
A free, browser-based tool to trim and reorder CSV columns. Upload or paste a CSV, tick the columns you want to keep, reorder them with up/down buttons, and get a clean CSV to copy or download. It's perfect for cleaning up exports that contain more columns than you need. Everything runs locally in your browser, so your data is never uploaded.
How to use it
- Upload a CSV file or paste it into the box on the left.
- Tick the columns you want to keep and untick the ones to drop.
- Use the up/down buttons to reorder the columns as needed.
- Copy the result or download the trimmed CSV.
Common use cases
- Removing unnecessary columns from a CRM or analytics export before import.
- Reordering columns to match the format another tool expects.
- Sharing only specific columns while keeping sensitive fields out.
