Flat per-line space prefix
The op is `" ".repeat(n) + line` applied to every line. There is no tab support, no per-line logic, and no nested-list awareness - already-indented lines get additional spaces, not a preserved hierarchy.
For padding to a target width (short lines get more fill, lines already at width pass through), use Left pad instead. For fixed leading text that is not spaces, use Add a prefix with the text you want.
Non-numeric or negative values collapse to zero indent: empty Spaces field, `0`, or `-2` all produce no change. Decimal values (`2.5`) are parsed as the integer part (`2`).
How to use indent each item in a list
- 1Paste your list into the input panel
- 2Set Spaces - the number of space characters to prepend (default `4`)
- 3Output prepends that many spaces to every line, including blanks
- 4To remove indentation later, use trim with Side set to Start only
- 5For tabs instead of spaces, use Add a prefix with an actual tab character in Prefix

What this tool actually does
One option, flat per-line space prefix.
Spaces only
The tool emits `U+0020` characters. For tab indentation, use Add a prefix with an actual tab character pasted into the Prefix field.
Applies to every line
Including blanks and lines that already have leading whitespace. A line that was already 2-space indented becomes 6-space indented if you add 4 more.
Not a nesting tool
Indent is additive and flat. To build nested hierarchies (Markdown sub-bullets, YAML nesting), you need a parser-aware tool - this isn't it.
Negative / non-numeric → zero
Empty field, `0`, negative numbers, and `abc` all produce no change. Decimals are floored to integers.
Blank lines become leading spaces
With Spaces `4`, an empty line becomes ` ` (four spaces). Chain Remove empty lines first if blank-but-not-empty lines would cause problems in your target format.
Worked example
Spaces `2` prepends two spaces to every line.
Item 1 Item 2 Item 3
Item 1 Item 2 Item 3
Settings reference
How the Spaces option shapes the output using the sample above.
| Setting | What it does | Effect on the sample |
|---|---|---|
| Spaces: `4` (default) | Prepends four spaces to every line | ` Item 1` / ` Item 2` / ` Item 3` |
| Spaces: `2` | Prepends two spaces | ` Item 1` / ` Item 2` / ` Item 3` |
| Spaces: `0` (or empty) | No change - emits lines verbatim | `Item 1` / `Item 2` / `Item 3` |
| Spaces: negative or non-numeric | Treated as zero | Same as above |
| Blank-line behaviour (automatic) | Empty lines get Spaces × space prepended | Empty line → ` ` (4 spaces, with default) |
