String Transforms

Reshape text: change case, trim, replace, join, split, or apply a regular expression.

Each takes an input (or the piped value) and returns it upper-cased, lower-cased, or with leading and trailing whitespace removed.

Literal (not regex) find-and-replace within the input.

Field	Description
input	The text to operate on.
search	The literal substring to find (`find` is accepted as an alias).
replace	What to substitute in. Omit or blank to delete the matches.

Joins a list of values in order. Each entry is templated; blank entries are skipped.

Splits the input on a delimiter and returns one part by index.

Field	Description
input	The text to split.
delimiter	The separator. If blank, the whole input is returned.
index	Which part to return (0-based). Negative counts from the end — `-1` is the last part. Defaults to 0.

Applies a regular expression. With a replacement it replaces all matches; without one it extracts a capture group.

Field	Description
input	The text to match against.
pattern	The regular expression.
replacement	If present, every match is replaced with this (replace mode).
group	In extract mode, which capture group to return. Defaults to group 1 (or the whole match if there are no groups).
