About the CSV Viewer / Editor
CSV files are everywhere — exports from databases, spreadsheets, and analytics tools — but reading raw comma-separated text is painful, and opening a small file in a full spreadsheet app is overkill. This tool turns pasted or uploaded CSV into a clean, sortable table you can actually read, and lets you edit cells, add or delete rows, and rename columns right in the browser.
When you're done, copy or download the result as CSV. Because everything runs locally, you can inspect and tidy up sensitive exports without uploading them anywhere.
A quick alternative to a spreadsheet
For quick jobs — checking what's in an export, fixing a few values, sorting by a column, or trimming rows — a full spreadsheet program is slow to open and can mangle CSVs (turning long numbers into scientific notation, or stripping leading zeros). This viewer keeps your data as plain text and shows it exactly as it is, which is safer for IDs, codes, and phone numbers.
Sorting and editing
Click a column header to sort by it; numeric columns sort by value and text columns alphabetically. Edit any cell inline, add rows for new records, and delete rows you don't need. The export reflects your edits with proper CSV quoting, so the file stays valid.

- 1Paste CSV text or upload a .csv file.
- 2View it as a table and sort by clicking column headers.
- 3Edit cells, add or delete rows, and rename columns.
- 4Copy or download the updated CSV.
Frequently asked questions
Can I edit the data, not just view it?
Yes. Cells are editable inline, and you can add or delete rows and rename column headers, then export the result.
Will it mangle IDs or leading zeros like a spreadsheet might?
No. Values are kept as plain text, so long numbers, codes, and leading zeros are preserved exactly rather than being reformatted.
What delimiters are supported?
Comma is the default, and you can choose others such as semicolon or tab for files that use them.
How do I sort the table?
Click a column header. Numeric columns sort by their values and text columns sort alphabetically; click again to reverse the order.
Is my file uploaded to a server?
No. Parsing, editing, and export all happen in your browser, so even sensitive CSVs stay on your device.
