linexcel 1.7.0

[1.7.0] — 2026-09-07

Fixed

• A dynamic-array formula no longer reads as #SPILL!. The recalculation
  engine does not compute array spill, so a spilled formula (one written to
  spill across a range) came back as #SPILL! even when Excel had stored a
  real value for it. #SPILL! is now treated as not recalculated rather than
  as a result: the value the file actually stores is shown instead, so a cell
  that has a number in Excel no longer appears to have errored.

Changed

• The viewer lets you pick a sheet again. The graph toolbar that floats
  over the canvas sits above it now, so the sheet dropdown is clickable instead
  of the mouse always grabbing the graph underneath.
• The graph opens organic (fcose) whatever its size. Previously a large
  graph fell back to the hierarchical flow layout, which is often unreadable
  once the file is big; flow stays one click away, organic is the default.
• The "should take" estimate counts formulas, not just their weight. A
  workbook's likely runtime now reflects the number of formulas as well as how
  much formula there is, so the printed estimate is closer to reality for
  formula-heavy files.
• A run that overruns its estimate says so, with a way out. If analysis
  goes past four times the estimate (and at least a minute), the console prints
  one actionable note naming --time-budget and -v instead of letting a long
  run pass in silence.

Performance

• A failed full recalculation no longer turns minutes into hours. Blanking
  the formulas that stop the engine used to read them back one cell at a time —
  quadratic, the source of multi-thousand-second runs. The suspect scan now
  streams the sheet's XML instead (linear). A fresh run adds a small
  perf_probe helper for measuring where time goes.
