How to use Right-pad a List
- 1. Paste your list. Enter your items into the input pane, one per line. Any list you need extended with filler items at the end works here.
- 2. Enter a pad item. Type the value to insert after your list in Pad item, such as a placeholder word, a zero, or any repeated filler value.
- 3. Set the number of copies. Enter how many times the pad item should be inserted in Copies. That many copies of the pad item are appended after your original list.
- 4. Copy the padded list. The output pane shows your original items followed by the pad item repeated at the end. Copy the padded result wherever it is needed.
When to use Right-pad a List
Right-pad a List inserts one or more copies of a filler item at the end of a list. Use Right-pad a List whenever a list needs extra trailing placeholder entries after the real data ends.
- Filling out a table to a fixed row count. A layout expects a fixed number of rows and your data has fewer, so right-padding with a blank placeholder brings the list up to the required count.
- Aligning a shorter data series for a chart. One series in a comparison chart ends earlier than the others, and right-padding it with a repeated placeholder value keeps all series ending at the same length.
- Adding trailing spacer lines to a printed list. A printed page has extra room at the bottom that should hold blank lines to match a fixed layout, which right-padding with an empty pad item fills in.
- Appending a repeated closing marker. A list needs the same closing marker repeated several times at the end for a specific format, which setting the pad item to that marker and picking several copies handles directly.
