The node supports three input sources:
| Source | Description |
|--------|-------------|
| Specific Field | Process a single named field from the input |
| All String Fields | Process all string fields in the input item |
| Custom Text | Process custom text (can use expressions) |
Controls whether matching is case-sensitive (enabled by default). The screenshot below shows Case Sensitive OFF, allowing hello to match Hello:
!Case insensitive text replacement in n8n workflow
Case Sensitive OFF: "hello" matches "Hello" in the input
Controls whether all matches are replaced (enabled by default). The screenshot below shows Replace All OFF, replacing only the first occurrence:
!Replace first occurrence only option in n8n Text Replace
Replace All OFF: Only the first "Hello" is replaced
When processing all string fields, this option includes fields in nested objects and arrays.
Instead of modifying the original field, output the result to a new field with a custom name.
An example workflow is included in the package. Import example-workflow.json` to see the node in action with all three operations demonstrated.
