You can use the following syntax to extract the filename from a full file path in Excel:

=TEXTAFTER(A2, "\", -1)

This particular formula extracts the filename from the full file path in cell **A2**.

For example, suppose cell **A2** contains the following full file path:

**C:\Users\bob\Documents\current_data\baseball_data.xlsx**

This formula will return:

**baseball_data.xlsx**

The following example shows how to use this formula in practice.

**Example: Extract Filename from Full Path in Excel**

Suppose we have the following column of full file paths in Excel:

Suppose we would like to extract only the filename from each file path in column A.

We can type the following formula into cell **B2** to do so:

=TEXTAFTER(A2, "\", -1)

We can then click and drag this formula down to each remaining cell in column B:

Column B now contains just the filename from each full file path in column A.

**How This Formula Works**

The **TEXTAFTER **function in Excel extracts all text in a cell after a specific character or substring.

This function uses the following syntax:

**TEXTAFTER(text, delimiter, [instance_num], [match_mode], [match_end], [if_not_found])**

where:

**text**: Text to search**delimiter**: Character or substring to extract text after**instance_num (optional)**: Instance of delimiter after which to extract text (default is 1)**match_mode (optional)**: 0 = case-sensitive (default), 1 = case-insensitive**match_end (optional)**: Treat end of text as delimiter (disabled by default)**if_not_found (optional)**: Value to return if delimiter is not found

Recall that we used the following syntax to extract the text after the last space in a cell:

=TEXTAFTER(A2, "\", -1)

By using a value of **-1** for the **instance_num** argument, we were able to specify that we wanted to extract the text after the **last** instance of a slash.

This is equivalent to extracting just the filename from the path, since the filename occurs after the last slash in the string.
