CSV Viewer & Editor
Open a CSV file in a table, sort it, edit cells, add or remove rows and columns, then export it again. Free, no signup, nothing uploaded.
How to open and edit a CSV file
Open Your CSV
Drag and drop a .csv file or click to choose one. Or start blank to build a table from scratch.
View and Edit
See it as a table. Click any cell to edit, sort by a column, filter rows, and add or remove rows and columns.
Export
Pick a delimiter and download the edited file as a clean CSV.
Work With CSV Without a Spreadsheet
A CSV file is just rows of text separated by commas, which makes it easy for programs to read but awkward for a person to scan or fix. Opening it in a full spreadsheet app is often more than you need for a quick look or a small edit.
This tool turns the file into a clean table right in your browser. Headers stay pinned to the top, rows are numbered, and you can click any cell to change it. Sort a column to find what you need, filter the rows by a search term, and add or remove rows and columns with a click. Quoted fields, commas inside values, and line breaks are all handled correctly.
When you are done, export it back to CSV with the delimiter you want. It all runs on your device, so the data never leaves your computer.
