▤ Plain Text to CSV Column Splitter
Paste lines of plain text with a consistent delimiter — even a multi-character one like runs of spaces — and split them into properly quoted CSV columns. Nothing leaves your browser.
Delimiter can be a literal string (matched exactly, any length) or a
regex pattern (e.g.
\s+ for runs of spaces/tabs, or \s*\|\s*
for a pipe with optional surrounding spaces). Avoid capturing groups ( ) in a regex
pattern — String.split() inserts captured text as extra columns; use (?:...)
if you need grouping without capturing.
