# 1 Basics

**ISBLANK** is a common spreadsheet function (Excel, Google Sheets) — checks if a cell is empty. Returns **TRUE** when the cell is empty; **FALSE** when it contains anything (including empty strings, formula results, etc.).

### Syntax

```excel formula theme={"theme":{"light":"github-light","dark":"github-dark"}}
ISBLANK(value)
```

* **value**: the cell or expression to check.

### Examples

#### Example 1: empty check

\[Field 1] in the first record has no content.

```excel formula theme={"theme":{"light":"github-light","dark":"github-dark"}}
=ISBLANK([Field 1])
```

Result: **TRUE**

#### Example 2: cell with text

\[Field 1] in the first record contains **"Hello"**.

```excel formula theme={"theme":{"light":"github-light","dark":"github-dark"}}
=ISBLANK([Field 1])
```

Result: **FALSE**
