# How To: Handle Null or Empty Values

Use null-handling attributes when blank fields would confuse the reader.

### Problem

You need to display something meaningful when a field is null or empty.

### Solution 1: `nullprefix` and `nullpostfix`

**Display `N/A` for empty values:**

```
<column nullprefix="N/A">Optional_Field__c</column>
```

**Display `TBD` for empty dates:**

```
<p>Ship Date: {{!Opportunity.Ship_Date__c format-date="MM/dd/yyyy"}}</p>
```

If the field is null, this shows nothing.

**Better:**

```
<column nullprefix="TBD" format-date="MM/dd/yyyy">Ship_Date__c</column>
```

### Solution 2: Conditional Rendering

**Show different text for null:**

```
<!--{{!
<lineitemsSOQL>
<soql>SELECT Title FROM Contact WHERE AccountId = '{{!Account.Id}}'</soql>
<column render="RECORD.Title==null,No title provided,RECORD.Title"></column>
</lineitemsSOQL>
}}-->
```

### Solution 3: `allprefix` and `allpostfix`

**Add symbols regardless of null:**

```
<column allprefix="$" format-number="#,###.##">Optional_Amount__c</column>
```

**Result:** The `$` still appears even when the field is null.

### Tips

* Use `nullprefix` when you need placeholder text.
* Use `allprefix` when symbols should always appear.
* Combine with `render` for more complex null logic.
* Standard `prefix` and `postfix` do not render for null values.
