# tNormalize Standard properties

These properties are used to configure tNormalize running in the Standard Job framework.

The Standard tNormalize component belongs to the Processing family.

The component in this framework is available in all Talend products.

## Basic settings

| Properties | Description |
| --- | --- |
| Schema and Edit<br>Schema | <ul> <li> <p>A schema is a row description. It defines the number of fields            (columns) to be processed and passed on to the next component. When you create a Spark            Job, avoid the reserved word <kbd>line</kbd> when naming the            fields.</p> <p>Click <span>Edit        schema</span> to make changes to the schema. If the current schema is of the <span>Repository</span> type, three options are available:</p> <ul> <li> <p> <span>View schema</span>: choose this                option to view the schema only.</p> </li> <li> <p> <span>Change to built-in property</span>:                choose this option to change the schema to <span>Built-in</span> for local changes.</p> </li> <li> <p> <span>Update repository connection</span>:                choose this option to change the schema stored in the repository and decide whether                to propagate the changes to all the Jobs upon completion.</p> <p>If you just want to                propagate the changes to the current Job, you can select <span>No</span> upon completion and choose this schema metadata                again in the <span>Repository Content</span>                window.</p> </li> </ul> </li> <li> <p> <span>Built-In</span>: You create and store the schema locally for this component                only.</p> </li> <li> <p> <span>Repository</span>: You have already created the schema and stored it in the                Repository. You can reuse it in various projects and Job designs.</p> </li> </ul> |
| Column to normalize | Select the column from the input flow which the normalization is<br>based on. |
| Item separator | Enter the separator which will delimit data in the input<br>flow.<br><br>Information noteNote:<br><br>The item separator is based on regular expressions, so the<br>character *"."* (a special<br>character for regular expression) should be avoided or used<br>carefully here. |

## Advanced settings

| Properties | Description |
| --- | --- |
| Get rid of duplicated rows from output | Select this check box to deduplicate rows in the data of the<br>output flow. |
| Use CSV parameters | Select this check box to include CSV specific parameters such as<br>escape mode and enclosure character. |
| Discard the trailing empty strings | Select this check box to discard the trailing empty<br>strings. |
| Trim resulting values | Select this check box to trim leading and trailing whitespace from<br>the resulting data.<br><br>Information noteNote:<br><br>When both Discard the trailing empty<br>string and Trim resulting<br>values check boxes are selected, the former works<br>first. |
| tStatCatcher Statistics | Select this check box to gather the Job processing metadata at the Job level as well as<br>at each component level. |

## Global Variables

| Variables | Description |
| --- | --- |
| Global Variables | ERROR\_MESSAGE: the error message generated by the<br>component when an error occurs. This is an After variable and it returns a string. This<br>variable functions only if the Die on error checkbox is<br>cleared, if the component has this checkbox.<br><br><br>NB\_LINE: the number<br>of rows read by an input component or transferred to an output component. This is an<br>After variable and it returns an integer.<br><br>A Flow variable functions during the execution of a component<br>while an After variable functions after the execution of the component.<br><br>To fill up a field or expression with a variable, press Ctrl+Space to access the variable list and choose the variable to use from<br>it.<br><br>For more information about variables, see [Using contexts and variables](https://help.qlik.com/talend/r/en-US/8.0/studio-user-guide/contexts-and-variables). |
