Comma Separator Tool Custom Delimiters & List Formatting
Format lists with any separator — comma, pipe, semicolon, or custom quotes instantly.
10 Separator Styles
Comma, semicolon, pipe, space, dash, newline, tab, dot, plus, no separator — plus a free-text custom separator input for anything else.
Highlight View
Switch to Highlight mode to see each separator visually marked in red between items — so you can confirm the exact output format before copying.
Auto-Detect Input
Auto-detect mode intelligently identifies whether your input uses commas, semicolons, pipes, tabs, or newlines — and splits accordingly without manual configuration.
Clean Options
Trim whitespace, remove empty items, deduplicate, and sort A–Z — all toggleable independently. Clean before you format for perfect output every time.
Item Preview Chips
Every item appears as a numbered chip — click any chip to copy it directly. Instantly see what's in your list after cleaning and deduplication.
All Languages + RTL/LTR
Arabic, English, Chinese, Japanese, Hebrew — all Unicode scripts work perfectly. Toggle RTL/LTR for correct text direction in both the input and output panels.
