Streamlined approvals, Excel skill library, and faster workbook writes

What's new

Skill library now available in the Excel add-in

Firm-saved and personal saved prompts are now accessible directly from the CoAudit pane in Excel. Browse your firm's authoring conventions, invoke prompts with @-mentions, or save new ones — without switching to the web app.

Approval controls redesigned for clarity and speed

Several improvements to how CoAudit presents pending actions for your review:

"Approve all" now settles every pending action in one click. Previously, certain actions (file deletions, moves, patches that merge cells or clear evidence) were excluded and required one-by-one handling. They're now included. What each action will do — "merges cells," "clears evidence," "clears reasoning" — is stated in plain text on each row and in the strip summary so you know exactly what you're authorizing before clicking. All confirm buttons are consistently blue; the nature of the action is communicated in words, not button color.
Each pending action has its own quick Approve button. Alongside the existing Skip button on each collapsed row, a matching Approve button lets you settle individual actions without expanding the card.
Clickable cell-reference badges show where CoAudit will write. Each pending write displays cell-reference pills (e.g., "B5:D12 · 18 cells"). Clicking one selects that range in your workbook so you can inspect the target area before approving — nothing changes until you confirm. When any pending write lacks a sheet qualifier, all badges become plain text so a navigation click can't accidentally retarget a waiting write to the wrong sheet.
Applied-writes summary after each AI turn. Once CoAudit finishes writing, an "Applied N cells in M writes" line appears with clickable badges for each range — a quick way to see and navigate to everything that just landed.
Approval cards no longer get permanently stuck. On some machines, reading the workbook before showing the Approve/Decline buttons could stall indefinitely, leaving the card unresponsive with no way out. After a short wait, decision buttons now become available regardless, with a clear note describing what approving will do.

Performance

Citations highlight faster after CoAudit writes. When CoAudit fills in multiple cited cells at once, all citation highlights now resolve together in a single request rather than sequentially. On a heavily cited grid this is the difference between highlights appearing in seconds versus a minute or more.
Workbook writes complete faster for large batches. CoAudit now groups multiple cell writes, format loads, and container saves into fewer Excel round-trips. Larger workpaper fills — especially those spanning many rows or columns — complete noticeably faster.

Bug fixes

Numbers now land as numbers. When CoAudit writes a value like "5000," it now correctly becomes a number in Excel — picked up by SUM formulas, sortable, and format-aware — rather than text that formulas skip.
Dates written to date-formatted columns become proper Excel dates. A date string written to a column already formatted as a date (or declared with a date format) now converts to an Excel date value — sortable and formula-compatible — rather than quote-prefixed text.
Lasso dates from Excel sources write as proper date values. When you Lasso-select a date from an Excel or CSV source, the captured date now writes to your workbook as an Excel date in your locale's format, rather than as a text string.
No more false "overwrites existing data" warning for dates. CoAudit was incorrectly flagging a write as destructive when re-sending a date that already matched what was in the cell. Re-sending the same date is now correctly recognized as a no-op.
Import retry stays available in the Files view. The option to retry a failed document import was disappearing when you were on the Files tab; it now remains accessible.
Current view is preserved when importing context. Importing a context no longer navigates away from whichever view (Files, Documents, Viewer) you were on.
