# Bulk column header edits

## Why bulk column header edits

Sometimes you need to make the same edit to all of your column headers. If you have many columns, it take a lot of time to update each column header one at a time. For example, after constructing a pivot table, you might want to remove the aggregation type from the column header. Bulk column header edits let you update all of your column headers at once. 

## How to bulk update column headers

1. Open the `Data` tab.
2. Click `Rename Columns`.
3. Use the taskpane to convert the column headers to uppercase/lowercase, or find and replace text the column headers.
