CSV viewer

Paste text or load a .csv / .tsv file — header row optional; click column titles to sort.

Delimiter auto: more tabs than commas → tab; else comma. Quotes "like this" supported. Files stay on your device.

Fast way to inspect tabular data

A CSV viewer is helpful when you want to check column names, sort rows, or confirm that a spreadsheet export parsed correctly. It is especially useful when a file opens as a wall of text and you need a table view in seconds.

Delimiter and quoting issues

Many data problems start with the wrong delimiter or a quoted field that contains a comma, tab, or line break. This tool is good for spotting those issues early, before you import the data into a database or analytics workflow.

Quick data inspection

Paste a spreadsheet export to verify column headers, spot delimiter issues, or sort a preview before importing into a database.

Privacy

Parsing occurs locally — large sheets may tax memory.

Before importing to a database

Paste an export preview to confirm column names, spot empty rows, and verify that quoted commas did not break fields. Fixing structure here prevents failed bulk imports downstream.

Delimiter surprises

European exports sometimes use semicolons because commas appear inside decimal fields. Toggle delimiter settings when column counts look wrong on first paste.

Quick start

  1. Paste CSV or TSV — Drop spreadsheet export text into the input area.
  2. Confirm delimiter — Toggle comma versus tab if columns look misaligned.
  3. Sort and browse — Click column headers to sort the preview table locally in your browser.
