The clipper test page

Test 1 — A table with a blank cell

The important one. Row three has no value under Seats, so a clipper that drops empty cells will shift Priority one column to the left.

Pass if: every row has four columns, and Priority sits under Support with Seats left empty.

| Plan     | Price | Seats | Support  |
|----------|-------|-------|----------|
| Free     | $0    | 1     |          |
| Team     | $12   | 5     | Email    |
| Business | $29   |       | Priority |

Test 2 — A wide table

Tests header detection and whether long tables survive without truncation.

Pass if: the header row arrives as a header (not as the first data row), and all six columns are present on every row.

Test 3 — Code blocks with language tags

The language tag is what makes syntax highlighting work. If it's lost, the code is still readable but the note is much less useful.

const clipped = articles
  .filter((a) => a.unread)
  .map((a) => ({ ...a, savedAt: Date.now() }));

def normalise(rows):
    return [r for r in rows if r.get("published")]

Pass if: the block above is fenced with ```javascript (or ```js) and the one below with ```python — not bare ``` fences, and not indented code.

Test 4 — Inline formatting inside a heading

Headings that contain code and emphasis are a common place for escaping mistakes — the backticks often survive as literal characters.

Using Array.prototype.flat() instead of recursive reduce

Pass if: the heading keeps its backticks and asterisks as Markdown formatting, with no stray escape characters like \`.

Test 5 — Nested lists

Indentation is easy to flatten, which destroys the structure.

• Extraction stage
  • Readability scoring
    • Paragraph density
    • Link-to-text ratio
  • Clutter rules
• Conversion stage
  • Table element parsing
  • Code language detection

Pass if: three levels of indentation survive, and the second top-level bullet is a sibling of the first, not a child of it.

Test 6 — Blockquote with a link and inline code

The cleanest test is to clip a page you actually care about and read it a week later. If you have to open the original to understand your own note, the clip failed. See the table guide for the | counting trick.

Pass if: the > prefix survives, the link keeps its URL, and the inline code stays inline.

Test 7 — Page furniture that should not appear

Everything above is content. This page also has a navigation bar, footer links, a copyright line and a legal disclaimer — none of which should end up in your note.

Pass if: your clipped note starts at the heading "The clipper test page" and ends before this page's footer, with no menu items, no disclaimer and no copyright line.
