+^Setting^Description^
+|Column|Select the column containing the delimited text to be split.|
+|Separator|Select the delimiting character to split the text by.  Options:  //Comma//, //Semicolon//, //Tab//, //Pipe//, //Tilde//, //Space//,//Line break//, and\\ //Custom// (and select the character from the dialog that displays). |

+\\
+=====Remarks=====
+Unlike the [[transformations:splitdelimitedtext|Split delimited text into columns]] action, in which you have to define the new columns to receive the split values, this action will create as many new rows as necessary to output all split values in the selected column.
+\\
+=====Examples=====
+**Example 1:** A value with 3 words, delimited with semicolons, will be split into three rows:\\
+**Source table:**
+^Row no ^Numbers ^
+| 1|one;two;three |
+\\
+**Action parameters:**
+> Column: "Numbers"
+> Delimiter: Semicolon
+\\
+**Result:**
+^ Row no ^ Numbers ^
+| 1|one   |
+| 1|two   |
+| 1|three |
+\\   \\
+**Example 2:** A column with multi-line text values.\\
+**Source table:**
+^ Location No ^ Location ^
+| 1| Mississauga \\ Ontario \\ Canada \\ North America |
+| 2| Cambridge \\ Massachusetts \\ United States \\ North America |
+\\
+**Action parameters:**
+> Column: "Location"
+> Delimiter: Line break
+\\

+| 2| Massachusetts  |
+| 2| United States  |
+| 2| North America  |
+\\ \\
+**Example 3:** Split out Order IDs into rows to create unique Customer-Order ID records.\\
+**Source table:**
+^Customer ID^Order IDs^
+|CUST001  |ORD001, ORD005, ORD010  |
+|CUST002  |ORD002, ORD003, ORD009  |
+|CUST003  |ORD004, ORD006, ORD007, ORD008  |
+\\

+|CUST001  |ORD010  |
+|CUST002  |ORD002  |
+|CUST002  |ORD003  |
+|CUST002  |ORD009  |
+|CUST003  |ORD004  |
+|CUST003  |ORD006  |
