Pad Lines
Left, right, or center-pad every line to a target width with a fill character, or zero-pad numeric lines.
Pad or align every line to a fixed width
Fixed-width columns help when aligning log excerpts, building simple tables in plain text, or preparing batch ID fields. Paste multi-line text, set a target character width, and pad on the left, right, or center with any fill character. Integer-only lines can be zero-padded for consistent numeric columns.
Alignment behavior
- Left keeps text at the start and pads on the right (classic left-aligned column).
- Right pads on the left so values line up on the right edge.
- Center splits padding evenly when possible.
For single-string Unicode padding see Left Pad Unicode and Right Align Unicode.
Frequently Asked Questions
What happens if a line is already longer than the target width?
That line is left unchanged so you do not lose data.
How does zero-padding work?
When enabled, lines that contain only an integer (optional leading minus) are padded with zeros on the left to reach the target width, similar to spreadsheet fixed-width IDs.
Can I use a custom pad character?
Yes. The first character of the pad field is used for alignment padding (zero-padding always uses 0).
