Automate Your Month End Close Checklist in Excel with Claude AI
This course gives you a Claude prompt that turns a plain list of close tasks into a structured Excel checklist with owners, deadlines, status tracking, and an automatic completion percentage. Paste your tasks, get a ready-to-use tracker back — no VBA, no macros, just formulas and data validation.
The Completed Close Tracker in Excel
Here is what Claude produces. Each close task has an assigned owner, a target deadline, and a status column driven by data validation. The final row calculates overall completion automatically.

WD = working day after month-end. Status uses Excel data validation with four options: Not Started, In Progress, Pending, Complete. A summary row (not shown) calculates % complete using COUNTIF.
Every task gets an owner, deadline, and status — nothing falls through the cracks
Status column uses data validation so the team picks from a fixed list, not free text
A COUNTIF formula calculates overall completion percentage in real time
Claude builds the checklist from whatever task list you provide. The more specific your input, the more useful the output. Write out every step your team performs during the close — even the ones that seem obvious. Here is the minimum input layout:

01
List every task in close order
Sequence matters. Tasks that depend on earlier steps should come later. If bank reconciliation must finish before the trial balance review, list it first.
02
Assign a named owner to each task
Use actual names or roles, not "TBD". Claude uses these to populate the Owner column. If a task has no clear owner, decide before prompting — that's a process gap, not an AI problem.
03
Set deadlines as working days after month-end
Using WD+1, WD+2 etc. makes the checklist reusable every month. Claude will include a cell at the top where you enter the actual month-end date, and deadlines calculate from there.
04
Note dependencies between tasks
If the trial balance can't start until accruals are posted, say so. Claude can add conditional formatting that greys out tasks whose prerequisites aren't complete.
Tip: Include tasks that are often forgotten — clearing suspense accounts, updating the depreciation schedule, reconciling intercompany balances. If you need a dedicated template for depreciation, see the fixed asset depreciation course.
The Claude Prompt for Building a Month-End Close Checklist
Copy this prompt into Claude. Replace the bracketed task list with your own close steps. Claude will return a structured Excel-ready checklist with formulas for status tracking and completion percentage.
Prompt — paste into Claude
I need a month-end close checklist in Excel. Below are my close tasks in the order they should be completed.
CLOSE TASKS:
[Paste your task list here — one task per line, with owner, deadline, and any dependencies]
Requirements:
- Create an Excel table with columns: #, Task, Owner, Deadline (working days after month-end), Status, Notes.
- The Status column should use data validation with exactly four options: Not Started, In Progress, Pending, Complete.
- Add conditional formatting: green fill for Complete, blue for In Progress, yellow for Pending, red for Not Started.
- At the top of the sheet, include a cell where I enter the actual month-end date. Deadline dates should calculate from that cell using WORKDAY.
- At the bottom, add a summary row that calculates: total tasks, tasks complete, % complete (using COUNTIF).
- Add a second summary showing tasks by owner with their completion count.
- Do NOT invent tasks I haven't listed. Do NOT add placeholder data. Only use the tasks I've provided.
- Do NOT use VBA or macros — formulas and data validation only.
- Format the output as a tab-separated table I can paste directly into Excel.
Why a Structured Close Checklist Matters
The month-end close is a sequence of dependent tasks under a tight deadline. When the checklist lives in someone's head or in a scattered email thread, tasks get missed, deadlines slip, and the team scrambles. A structured tracker in Excel solves three problems at once: it makes task ownership visible, it shows real-time progress to leadership, and it creates a repeatable template for next month.
The prompt above produces a checklist you can reuse every period by simply updating the month-end date cell. All deadlines recalculate automatically. If your close includes reconciling the accounts payable aging report, that task slots into this checklist as one line item with its own owner and deadline.
Common Close Checklist Mistakes
A
B
1
Mistake
Consequence
2
No named owner per task
Tasks sit unfinished because everyone assumes someone else is doing them
3
Free-text status instead of a fixed list
COUNTIF formulas break because "Done", "Completed", and "Complete" are three different values
4
Hardcoded deadline dates
You have to re-enter every deadline each month instead of recalculating from one cell
5
Dependencies not documented
Someone starts the trial balance before accruals are posted and has to redo it
Frequently Asked Questions
What tasks should a month-end close checklist include?
A typical checklist covers bank reconciliation, AP and AR reviews, accrual entries, intercompany eliminations, fixed asset depreciation, revenue recognition, trial balance review, and financial statement preparation. The exact list depends on your organisation's complexity.
Can Claude generate the close checklist from my company's existing process?
Yes. Paste your current close steps into the prompt and Claude will restructure them into a trackable Excel checklist with columns for owner, deadline, status, and notes. It will not invent steps you haven't provided.
How do I track completion percentage automatically in Excel?
Claude builds a COUNTIF-based formula that counts rows marked "Complete" and divides by total tasks. This updates in real time as your team changes each task's status.
Does this replace close management software?
No. This is for teams that manage the close in spreadsheets and need a faster way to build and maintain the checklist. If you use dedicated close software, this template can serve as a lightweight backup or secondary tracker.
