3. Pre-Built Formulas & Calculation Logic

Target Cell / Range	Formula Name	Exact Formula (Excel / Google Sheets)	Calculation Purpose
`L2:L14` (Calculated Field)	Variance Hours	`=L2-K2`	Calculates difference between Actual and Budgeted hours per audit.
`P2`	Total Audits	`=COUNTA(A2:A14)`	Counts total scheduled audits in the master plan.
`P3`	Total Budgeted Hours	`=SUM(K2:K14)`	Aggregates total allocated audit hours for capacity planning.
`P4`	Total Actual Hours	`=SUM(L2:L14)`	Aggregates total expended audit hours to date.
`P5`	Hours Variance %	`=(P4-P3)/P3`	Computes overall resource utilization variance against budget.
`P6`	Completed Audits	`=COUNTIF(M2:M14, "Completed")`	Counts audits that have achieved completion status.
`P7`	In-Progress Audits	`=COUNTIF(M2:M14, "In Progress")`	Tracks active audit engagements currently underway.
`P8`	Critical Risk Audits	`=COUNTIF(O2:O14, "Critical")`	Identifies total high-exposure audits requiring heightened oversight.
`P9`	Avg Risk Score	`=AVERAGE(G2:G14)`	Computes portfolio average risk exposure score.

6. Setup & Export Guide for Excel & Google Sheets

Step 1: Export Data to CSV

Copy the Markdown table data from Section 2 (Master Data Spreadsheet Table).
Paste the data into a plain text editor (e.g., Notepad or TextEdit) and save the file as internal_audit_plan.csv. Alternatively, copy directly into a blank worksheet cell A1.

Step 2: Import into Microsoft Excel

Open Microsoft Excel and create a new blank workbook.
Navigate to the Data tab > Get Data > From File > From Text/CSV.
Select your saved internal_audit_plan.csv file.
Verify the delimiter is set to Comma and click Load.
Format the header row with a dark navy fill (#1B365D) and white bold text. Apply gridlines and set columns G, K, and L to right-alignment.

Step 3: Import into Google Sheets

Open Google Sheets and open a new blank spreadsheet.
Go to File > Import.
Upload the internal_audit_plan.csv file.
Select Replace current sheet or Insert new sheet, ensure separator character is detected as Comma, and click Import data.

Step 4: Apply Data Validation Rules

Highlight columns requiring drop-down menus (e.g., Status in range M2:M100).
In Excel: Go to Data > Data Validation > Allow: List > Source: enter comma-separated list values (e.g., Not Started, In Progress, Completed, Deferred, Cancelled).
In Google Sheets: Go to Data > Data validation > Add rule > Criteria: Dropdown (from a range) or Dropdown and input the allowed string values.

Step 5: Implement Formulas & Dashboard

Insert a new worksheet tab named Dashboard.
Map the KPI summary metrics using the exact formulas specified in Section 3 and Section 5.
Apply Conditional Formatting to the Status and Priority columns to visually highlight Critical (Soft Red fill) and Completed (Soft Green fill) attributes.
Save the finalized workbook as .xlsx (Excel) or ensure changes are synced in Google Drive.
