About Text Interval Generator
This tool inserts a separator (comma, pipe, newline or custom string) between each line of text.
It is useful for converting line lists to comma-separated values, building SQL IN clauses or formatting text for APIs.

|---|---|---|
| CSV export | , | item1,item2,item3 |
| SQL IN clause | ',' | 'a','b','c' |
| Log parsing | | | field1|field2|field3 |
| TSV export | \t | col1\tcol2\tcol3 |
| JSON array | ", " | "a", "b", "c" |
Frequently Asked Questions
- What separators can I use?
- Any string works: comma, pipe, semicolon, newline, tab, or custom text. Use for newline and for tab.
- How does it handle empty lines?
- Empty lines are preserved as empty entries. "a b" becomes "a,,b" with comma separator.
- Can I remove the separator from the last item?
- The tool adds separators between all lines. For SQL IN clauses or similar, you may need to trim the trailing separator manually.
- What about trailing whitespace?
- Line content is preserved as-is. Trim whitespace in your source text if needed before processing.
- How do I create an SQL IN clause?
- Enter your values one per line, use comma separator, then wrap output in parentheses: (value1,value2,value3).
- Can I join without any separator?
- Yes. Enter an empty separator to concatenate all lines directly without any characters between them.
