CSV Reader
Think of a CSV reader as your shortcut to making sense of messy data files. Instead of squinting at raw text packed with commas and line breaks, you get a clean, organized table with headers and row numbers that are easy to follow. Our tool handles CSV, TSV, and TXT files right in your browser, using sticky headers and alternating row colors so you never lose your place. Just drag and drop your file or paste the text to get started. You can sort any column with a click, toggle between table and raw views, and grab your results as soon as you are done.

How to Use This Free CSV Reader
You will be up and running in seconds. Just hit the Upload button, drag your file into the window, or paste your CSV text directly onto the screen. The tool automatically scans the first line to detect your delimiter, meaning it works seamlessly with commas, tabs, semicolons, or pipes. Once your data is ready, look at the top info bar to see your file name, row and column counts, and other key details at a glance.
Sort by Any Column
Organizing your data is as simple as clicking a column header. Click once to sort, and again to flip the order. The tool is smart enough to sort numbers by value and text alphabetically. Plus, your sorting only changes the view, so your original data stays perfectly intact for your next export.
Switch Between Table and Raw Views
Switch back and forth between a polished table and the raw text view whenever you like. The table view gives you helpful row numbers and alternating colors for easier reading, while the raw view shows you the exact layout of the original file if you need to check the formatting.
Search, Filter, and Analyze CSV Data
When you are dealing with thousands of rows, finding one specific entry can feel impossible. That is why the CSV Search tab filters your data in real time as you type. It scans every single cell, pulling matching rows into view regardless of which column the text is in. You will see the match count update live in the status bar, and you can download or copy just the filtered subset whenever you are ready.
Column Selection for Targeted Exports
Tailor your view using the Column Picker tab, which lists checkboxes for every column in your dataset. If you do not need a specific field, just uncheck it to hide it from the table instantly. This is perfect for targeted exports, as your downloads and copies will only include the columns you have kept visible. Use the Select All or Clear buttons to handle large files in a flash.
Per-Column Statistics
If you need a deeper look at your data, head over to the Summary tab for detailed per-column stats. You will find unique value counts, empty cell tallies, and string length ranges for every column. For columns that are mostly numeric, the tool also shows you the minimum, maximum, and average values. The four cards at the top keep you updated on the big picture, like total rows, columns, and file size.
Online CSV Reader with Transpose and Export
For some datasets, flipping everything on its side makes comparison much easier. The Transpose tab turns your columns into rows, putting field names on the left and displaying up to 50 data rows as horizontal columns. This is a lifesaver for wide files where you would otherwise be scrolling endlessly to compare a few records. You can even download this transposed layout as a fresh CSV file for other projects.
Privacy-First Browser Processing
Privacy is built-in because every operation happens right inside your browser. By using the browser File API and JavaScript, the tool parses your files locally without ever uploading them to a server or database. Your data stays on your machine and is never transmitted over the network. Once you close your tab, everything is wiped from memory, making this the perfect choice for handling sensitive financial records or private employee lists.
No Account Required
You get full access to every feature without having to register, log in, or pay a cent. There are no usage limits, premium tiers, or annoying watermarks on your exports. Feel free to open as many CSV files as you need and explore every tool for as long as you like, all for free.
