How to Use Split Strings

Splitting text by a delimiter (comma, newline, tab) usually means writing a script or doing it in a spreadsheet. The Split Strings tool does it in the browser: paste your text, choose or enter a delimiter, and get segments (often one per line)—no sign-up and no data sent to a server.

What does Split Strings do?

Split Strings is a free online tool that splits your text by a delimiter (comma, newline, tab, or custom) and outputs the segments, often one per line. It is used to parse CSV-like data, split on a specific character, or break a single line into a list for further processing. All processing runs in your browser; there is no upload, no storage, and no account required.

Key Features

• Delimiter choice — Comma, newline, tab, or any custom character or string. The text is split at each occurrence.
• Custom delimiter — Enter any character or string as the delimiter. Handy for pipe, semicolon, or multi-character separators.
• Any input — Paste or type any text. Choose the delimiter that separates your items. Multiple delimiters in a row may produce empty segments. No size limit for in-browser processing.
• Instant result — Paste, set delimiter, and see the segments (e.g. one per line). Copy when ready.
• Privacy-first — All processing happens in your browser. Your text is never sent to any server.
• No account — Use as often as you need without sign-up.

How to Use Split Strings

1. Open the Split Strings tool.
2. Paste or type your text (e.g. comma-separated or line-based).
3. Choose or enter the delimiter (comma, newline, tab, or custom). View the split result. Copy the result.
4. Paste into another tool (e.g. prefix, sort) or use the list as needed. Use the "Use tool" button on the docs page if you are reading this from the documentation.

Real Use Cases

• CSV-like data — Split a single line or block by comma, semicolon, or tab to get fields or values per line.
• Custom delimiter — Split on pipe, colon, or any character or string that separates your items.
• Single line to list — Break a comma- or semicolon-separated string into a vertical list for editing or other tools.
• Log or data parsing — Split log lines or structured text by a known delimiter for inspection or processing.
• Prepare for other tools — Split first, then use Prefix Text Lines, Sort Text, or Remove Duplicate Lines on the result.
• Import prep — Turn a delimited string into one-item-per-line for import or spreadsheet paste.

Why Use Split Strings Instead of Alternatives?

• vs. Split into Words — That tool splits on whitespace only. Split Strings uses any delimiter (comma, tab, custom).
• vs. Spreadsheet — When the data is in a text field or email, the browser tool is faster. No export or import.
• vs. Manual split — No need to add line breaks or copy each segment by hand. One paste, set delimiter, copy.
• vs. Scripts — No coding. Works in any browser.

Consecutive delimiters (e.g. two commas) create an empty segment. Trim or filter empty results if you do not want them.

Benefits for Data Users, Developers, and Writers

• Data users — Parse CSV-like or delimited text into a list. Prepare data for other tools.
• Developers — Quick split for config, env, or log parsing. No one-off script.
• Writers — Turn a comma-separated list into a vertical list for editing or formatting.

Common Mistakes

• Extra empty lines — Consecutive delimiters (e.g. two commas) create an empty segment. Trim or filter empty results if you do not want them, or use Delete Empty Lines after splitting.
• Wrong delimiter — Use the delimiter that matches your data (comma, tab, pipe, etc.). Wrong delimiter gives wrong segments.
• Expecting whitespace split — This tool splits on the delimiter you set. For whitespace-only split use Split into Words.
• Forgetting to copy — The result is not saved. Copy before closing the tab or refreshing.

Frequently Asked Questions

What does split strings do?

It splits your text by a delimiter (comma, newline, tab, or custom) and outputs the segments, often one per line.

Can I use a custom delimiter?

Yes. Enter any character or string as the delimiter. The text is split at each occurrence.

What input does it accept?

Paste or type any text. Choose the delimiter that separates your items. Multiple delimiters in a row may produce empty segments.

Is my text stored?

No. All processing happens in your browser. Your text is never sent to any server.

When should I use split by delimiter?

Use it to parse CSV-like data, split on a specific character, or break a single line into a list for further processing.

Why did I get extra empty lines?

Consecutive delimiters (e.g. two commas) create an empty segment. Trim or filter empty results if you do not want them.

Conclusion and Try the Tool

Split Strings gives you delimiter-split segments in seconds: paste, set delimiter, copy. No account, no server round-trip. For whitespace split use Split into Words, for joining lines use Join Text Lines, and for find-and-replace use Replace Text.
