About CSV Viewer
This CSV viewer turns a comma-separated file into a readable table you can sort and search. Open a .csv, .tsv, or .txt file, or paste the text directly, and it parses the rows the moment you do. It auto-detects the delimiter (comma, semicolon, tab, or pipe), or you can set it manually, and it correctly handles quoted fields that contain commas, line breaks, or escaped double quotes ("") — the parts that break a naive split-on-comma view.
Click any column heading to sort; number-looking columns sort numerically and text sorts naturally. The search box filters rows across every column at once, and the stats row shows column count, total rows, matching rows, and the detected delimiter. The first row is treated as a header by default, which you can turn off for headerless data.
Everything runs in your browser using the File API — your file is read locally and never uploaded to a server, so it works offline and keeps your data private. For very large files the table shows the first 1,000 matching rows to stay responsive; use the search box to narrow down to the rows you need.
Frequently asked questions
- Is my CSV file uploaded anywhere?
- No. The file is read directly in your browser with the File API and parsed locally. Nothing is sent to a server, so it works offline and your data stays on your device.
- Does it handle commas and line breaks inside quoted fields?
- Yes. The parser follows the standard CSV convention: fields wrapped in double quotes can contain the delimiter, line breaks, and escaped quotes (written as two double quotes, ""). Those are parsed as data, not as new columns or rows.
- What delimiters are supported?
- Comma, semicolon, tab, and pipe. By default it auto-detects the delimiter from the first line, but you can force a specific one from the dropdown if a file is unusual.
- Can I sort and search the data?
- Yes. Click a column heading to sort ascending, click again for descending, and once more to clear. Columns that look numeric sort as numbers. The search box filters rows by matching text in any column.
- Is there a file size limit?
- There is no hard limit, but the whole file is loaded into memory and the table renders the first 1,000 matching rows for speed. Very large files may load slowly; narrowing with the search box keeps the view fast.
- What if my file has no header row?
- Uncheck "First row is header" and every row is treated as data, with columns labeled Column 1, Column 2, and so on.
