Glide Computed Columns

Glide uses computed columns instead of cell formulas. Each computed column applies its logic to every row in the table.

Key Concept

Calculations in Glide are columns, not cell formulas. You build complex logic by chaining columns together - one column's output becomes another column's input.

Creating Computed Columns

1. In Data Editor, click a column header → "Add column right"
2. Name the column
3. Click the Type dropdown
4. Use the filter - type the column type (e.g., "math", "relation", "if-then") to find it quickly
5. Configure the column settings
6. Save

Math Columns

For arithmetic calculations.

Important: Use plain, human-readable column names as variables. No special escaping or symbols needed.

Example - calculating a total:

• Column A: "Quantity"
• Column B: "Unit Price"
• Math column formula: Quantity * Unit Price

Just type the column names naturally. Glide will recognize them.

Other examples:

• Price * 1.1 (add 10% markup)
• Total / Count (calculate average)
• End Date - Start Date (days between dates)
• Amount - Discount (apply discount)

Configure formatting: After creating a math column, set up proper display formatting:

• Decimal places: 0 for counts, 2 for currency
• Prefix: $ or € for money
• Suffix: %, kg, mi, hrs for units
• Thousands separator: Enable for large numbers

This makes the data instantly readable (e.g., "$1,234.56" instead of "1234.56").

If-Then-Else Columns

For conditional logic. Returns different values based on conditions.

Structure:

• IF [condition]
• THEN [value if true]
• ELSE [value if false]

Examples:

• Status emoji: IF Status is "Complete" THEN "✅" ELSE IF Status is "In Progress" THEN "🔄" ELSE "⏳"
• Priority color: IF Priority is "High" THEN "🔴" ELSE IF Priority is "Medium" THEN "🟡" ELSE "🟢"
• Overdue flag: IF Days Until Due < 0 THEN "Overdue" ELSE "On Track"
• Discount tier: IF Total > 1000 THEN "Gold" ELSE IF Total > 500 THEN "Silver" ELSE "Bronze"

You can chain multiple If-Then-Else for complex logic, or nest them.

Relation Columns

Connect rows between tables based on matching values.

Setup:

1. Create a Relation column
2. Select the target table
3. Choose which columns to match (e.g., "Customer ID" in Orders matches "ID" in Customers)

Types:

• Single relation: Returns one matching row
• Multiple relation: Returns all matching rows (for one-to-many)

Use relations to enable Lookups and Rollups.

Lookup Columns

Pull a value from a related row.

Setup:

1. Create a Lookup column
2. Select a Relation column as the source
3. Choose which column to pull from the related table

Example:

• Orders table has Relation to Customers
• Lookup column pulls "Customer Name" from the related Customer row
• Now each order shows the customer's name

Rollup Columns

Aggregate values across related rows.

Setup:

1. Create a Rollup column
2. Select a Relation column (usually a multiple relation)
3. Choose the aggregation: Count, Sum, Average, Min, Max
4. Select which column to aggregate (for Sum/Average/Min/Max)

Examples:

• Count of tasks per project
• Sum of order amounts per customer
• Average rating per product
• Max price in a category

Template Columns

Combine text and column values into formatted strings.

Example:

• Template: Hello, {Name}! Your order total is ${Total}.
• Columns can be inserted with the column picker

Great for:

• Formatted display text
• Email/message templates
• Generating URLs with dynamic values

Experimental Columns

Hero Icons

Generate icons from the Hero Icons library.

• Input: Icon name (e.g., "check-circle", "user", "folder")
• Output: Image URL for the icon
• Combine with If-Then-Else for dynamic icons based on status

Generate Text (AI)

Use AI to generate text based on other columns.

• Configure a prompt that references column values
• AI generates text for each row

Other AI Columns

• Image to Text: Extract text/info from images
• Text to Choice: AI categorization
• Text to Boolean: AI yes/no classification

Column Chaining Pattern

Build complex calculations by chaining simple columns:

Example: Order Status with Emoji

1. Relation: "Customer" → links to Customers table
2. Lookup: "Customer Name" → pulls name via Customer relation
3. Math: "Days Until Due" → Due Date - Today
4. If-Then-Else: "Is Overdue" → IF Days Until Due < 0 THEN true ELSE false
5. If-Then-Else: "Status Emoji" → IF Is Overdue THEN "🚨" ELSE IF Status = "Complete" THEN "✅" ELSE "📋"

Each column does one thing, and they build on each other.

Tips

• Name columns clearly - they become variables in other calculations
• Use the type filter - faster than scrolling through menus
• Chain simple columns - easier to debug than one complex column
• Test with sample data - verify calculations work before adding more
