Join Lines with Custom Delimiter
Join Lines with Custom Delimiter: Splits on line breaks and joins elements with the specified delimiter string.
About this join lines with custom delimiter
Join Lines with Custom Delimiter — browser-based utility.
How this tool works
Implements client-side Join Lines with Custom Delimiter operations. Splits on line breaks and joins elements with the specified delimiter string specifically designed for an sql developer joins a column of ids into a comma-separated list.
- Invisible Codepoint Detection: Scans character codepoint ranges against Unicode formatting categories (Cf, Cc), highlighting hidden characters.
- Unicode Normalization: Applies selected normalization form (NFC canonical composition, NFD decomposition, NFKC/NFKD compatibility).
- Pangu Spacing Heuristics: Evaluates character-pair boundaries via regex lookaheads, injecting half-width spaces between CJK ideographs and alphanumeric ASCII.
- Whitespace Collapsing: Cleans repeated spaces, trailing line spaces, and redundant blank lines according to user settings.
Worked example
Scenario: An SQL developer joins a column of IDs into a comma-separated list.
Sample input:

Limits and verification
Does not alter intentional whitespace within code blocks when code-preservation mode is selected. Carefully preserves directional formatting markers (RLM/LRM) when bi-directional Arabic/Hebrew text is explicitly preserved.
Examples demonstrate an expected workflow; they do not prove every input or every branch of an external specification. Check important results with an independent source before using them for money, security, compliance, safety, or irreversible file changes.
Browser processing boundary
Tool input is processed by code running in the browser and is not intentionally sent to a CZOA processing API. The page can still request ordinary site assets, analytics, or advertising when those services are enabled. Browser extensions and managed-device software remain outside this tool's control.

Frequently asked questions
How does Join Lines prepare each line?+
It splits at LF or CRLF, trims each line, removes empty results, and joins the retained lines. Whitespace-only lines are removed by trimming.
What did the browser fixture verify?+
With an explicit vertical-bar delimiter, spaced a and b separated by an empty line rendered as a|b.
What delimiter is used when the second control is empty?+
An empty secondary control falls back to comma followed by one space. A nonempty secondary value is used literally as the delimiter.
Does it preserve blank lines and indentation?+
No. Blank trimmed lines are filtered and each retained line is trimmed before joining, so original indentation and empty-line spacing are lost.
