Align Tab-Separated (TSV) Data into Clean Columns

Aligning Tab-Separated Data

Tab-separated values (TSV) are a common export format from spreadsheets, databases, and command-line tools like cut and awk. While tabs provide some visual spacing, the alignment breaks down when cell contents vary in length.

Before

id\tname\temail\trole
1\tAlice\talice@example.com\tadmin
2\tBob\tbob@company.org\tuser
3\tCharlie\tcharlie@test.io\tmod

After (space-padded)

id  name     email                role
1   Alice    alice@example.com    admin
2   Bob      bob@company.org      user
3   Charlie  charlie@test.io      mod

Step-by-Step

1. Select Tab as the input delimiter.
2. Choose Spaces as the output delimiter for clean visual spacing.
3. Enable Trim whitespace to remove any extra padding the exporter may have added.
4. The tool detects four columns and automatically calculates the width needed for each.

Why Tab Data Needs Re-Alignment

Tab stops are typically set at 8-character intervals in terminals, but this is a display convention rather than an actual column width. A 3-character cell and a 15-character cell both consume one tab, yet they push the next column to very different screen positions. Replacing tabs with measured space-padding ensures consistent alignment regardless of the viewer's tab-stop settings.
