About the Indent Text

Indenting a whole block is a two-second job in a code editor and a genuine chore anywhere else — a web form, a CMS, a chat box, a comment field. Doing it by hand means clicking to the start of every line.

This indents the whole block at once, in spaces or tabs, by whatever amount you set. The first line can be skipped, which is what you need when a block is being pasted after something already on that line. Blank lines can be left genuinely empty rather than filled with whitespace, which keeps a diff clean. Existing indentation is added to rather than replaced, so nesting is preserved.

Key features of the Indent Text

Spaces or tabs

Match whatever the destination file uses, since mixing the two is what makes indentation look wrong elsewhere.

Skip the first line

For a block being pasted after content already on that line, which is the common insertion case.

Blank lines left empty

No trailing whitespace on empty lines, which linters flag and diffs highlight.

Nesting preserved

Existing indentation is added to, so an already-nested block stays nested.

Any amount

One space or twelve, one tab or three — set it once for the whole block.

Frequently asked questions

Follow whatever the file already uses — mixing them is what causes indentation to look wrong in one editor and right in another. Python, YAML and most style guides specify spaces; Go and Makefiles require tabs.
