How to Reverse a Numbered List
If you ever need to reverse a numbered list in InDesign, (reversing either the list numbers or the items themselves), here’s how to do it.
First, if you need to reverse the numbering, keeping the list items themselves in place, you can use a script written by Jongware. Download it here.
Once you have the script installed, put your cursor in the first paragraph in the list and run the script.
The order of items is the same but the numbering now counts down.
Or, if you need to reverse the order of items, keeping the numbering the same, the solution depends on whether the items are in alphabetical order. If they are, you can simply use the Sort Paragraphs script that comes with InDesign.
Select all the paragraphs in the list, then run the script.
In the script dialog box, choose Reverse Sort and click OK.
If your items are not in alphabetical order, then you need the help of a spreadsheet like Excel or Google Sheets.
For example, to use Google Sheets, copy your list and paste it into Column B of a new Sheet.
In Cell A1, type 1. In Cell A2, type 2.
Then Shift-click to select both cells and drag the bottom right corner of the selection border down to fill Column A with as many numbers as you need for your list.
Then choose Data > Sort sheet by column A, Z–A.
The order of items will be reversed.
Now you can select your list items in Column B, and copy and paste them back into InDesign.
