Table Structures & Data Types

Habit Tracker (Main View)

This sheet uses a Gantt-style grid layout where each row represents a habit and each column represents a day or week. The structure is as follows:

Each column after the habit metadata represents a date (starting from the start date). The data type in these cells is Boolean (True/False) indicating whether the habit was completed that day.

Habit Details Sheet

Provides detailed configuration for each habit:

Formulas Required

The template leverages advanced Excel formulas to automate tracking and analysis:

• Habit Status Logic (Status Column): =IF(COUNTIF(HabitTracker!B:B, TODAY())=0, "Inactive", IF(AND(COUNTIF(HabitTracker!C:C, TODAY())>0), "Active", "On Break"))
• Streak Counter (Streak Analytics Sheet): =IFERROR(DAYS(TODAY(), MAX(IF(HabitTracker!D:D=TRUE, HabitTracker!A:A))), 0)
• Completion Rate (Dashboard Summary): =ROUND(AVERAGE(HabitTracker!G:G), 2) * 100
• Milestone Trigger: Uses nested IF and DATE functions to check if the habit has been performed on all days within a milestone window.

Conditional Formatting Rules

To enhance visual clarity, multiple conditional formatting rules are applied:

• Habit Progress Cells: Green fill for completed days (True), gray for missed days (False).
• Streak Highlighting: Yellow highlight for 3+ day streaks; red if break detected after 2 or more consecutive completions.
• Danger Zone Detection: If a habit is missed for >7 days, the row turns light red with bold text.
• Milestone Achieved: Green border and star emoji (⭐) when a milestone is reached.
