Column Sorter is a free online PaperStack tool for csv & data. Sort a CSV by any column, A–Z or high-to-low.
Column Sorter orders rows so you can rank amounts, alphabetize names, or put dates in sequence before you analyze or print.
You can use it on a phone, tablet, or computer. There is no sign-up, and processing runs in your browser so files and text are not uploaded to PaperStack for storage.
How Column Sorter is useful

Why use PaperStack for this
Many “free converters” ask you to upload a file to a server you do not control. PaperStack is built around browser-side processing: you open the page, do the work, and download or copy the result. That is the difference when the file is a payslip, a contract, a customer CSV, or a draft that is not public yet.
You also get a consistent layout across PDF, Word, image, CSV, and text tools, so the next job does not require learning a new app.
Frequently asked questions
Is Column Sorter free?
Yes. You can use it without creating an account or paying a subscription.
Are my files uploaded?
No. Processing runs locally in your browser. PaperStack does not need your file on a server to run the tool.
Does it work on mobile?
Yes. Use a modern mobile or desktop browser. Very large files are more comfortable on a laptop because they use more memory.
Can beginners use it?
Yes. Follow the steps above. If something looks wrong, keep the original file and try a milder setting (for example less compression).
