- src/utils/csv-to-table.js — pure module. Auto-detects the delimiter
(tab wins over comma; comma wins over semicolon). RFC 4180-style
parsing handles quoted fields, escaped quotes (""), and CRLF. Cells
are escaped for markdown tables (\\ for backslashes, \| for pipes,
newlines stripped). Alignment: a column is right-aligned when every
non-empty cell matches a numeric pattern AND there are ≥2 rows or
≥1 multi-character cell (single-char numbers like "1" alone are
too ambiguous to call as numeric — could be labels). Single-row input
produces a header-only table (no fabricated "Column N" labels, no
body).
- src/editor/smart-paste.js — paste handler now tries CSV first (it
needs no async), falls back to the existing URL → title flow.
Tests (30 new, tests/csv-to-table.test.js):
- detectDelimiter: tab > comma > semicolon, empty/non-string safe
- parseRows: simple, RFC 4180 quoted, escaped quotes, CRLF, multi-line
- escapeCell: pipes, backslash-first escaping, newline strip, null/number
- csvToTable: simple CSV, single-row (header-only), TSV, empty input
- alignment: numeric detection (≥2 rows OR ≥1 multi-char cell), currency,
percentages, text columns stay left
- escaping inside cells (pipes, newlines)
- ragged-row padding
- looksLikeCsv: true for tab/comma multi-row, false for single row,
column-count mismatch, prose, very short input
Full suite: 72 suites, 861 tests, lint+format clean.
