Two ways Import from Clipboard (and .tsv file import, which uses the same parser) loses data:

1. Leading zeros are dropped. ZIP codes, phone numbers and ids such as 00123, 0612345678 or 007 were inferred as INTEGER, so the created column stores 123, 612345678 and 7. A number with a leading zero is now inferred as TEXT. 0 itself and decimals like 0.5 are still numeric, and the type can still be changed in the dialog.

2. Multi-line cells from a spreadsheet break the rows. Excel and Google Sheets quote a copied cell that holds a line break, a tab or a quote, and double the quotes inside it:

name	note
Alice	"line 1
line 2"

The TSV parser split on every line break, so this became two rows, ["Alice", "\"line 1"] and ["line 2\""]. It now reads a quoted field when its closing quote ends the cell, meaning it's followed by a tab, a line break or the end of the text, and un-doubles "". Any other quote stays plain text, so 5" and "quoted" text are unchanged. CRLF inside and between cells works too.

Testing

• tests/utils/clipboardParser.test.ts (6 new tests):
  • a quoted cell with a line break;
  • doubled quotes and a tab inside a quoted cell;
  • CRLF inside and between quoted cells;
  • quotes that don't wrap the whole cell staying as text;
  • ZIP and phone columns inferred as TEXT while plain ids stay INTEGER;
  • 0 and 0.5 staying numeric.
• pnpm typecheck ✅, ESLint (no warnings) and Prettier on the changed files ✅.
• Full vitest run: 498 files, 8075 tests, all passing.
