🔗 EncodeUrl / JSON

Category: Utilities | Works in: Canvas Apps

Overview

EncodeUrl percent-encodes a string for safe use in a URL. JSON converts a value to a JSON-formatted text string.

Syntax

EncodeUrl( Text )
JSON( Value [, JSONFormat.IndentFour | JSONFormat.FlattenValueTables | ...] )

Simple Examples

1. Encode a title for a URL

EncodeUrl(Gallery1.Selected.Title)
// "Hello World" → "Hello%20World"

2. Open pre-filled mailto link

Launch("mailto:support@co.com?subject=" & EncodeUrl("Issue: " & Gallery1.Selected.Title))

3. Convert record to JSON string

JSON({ Name: "John", Age: 30 })
// → "{\"Name\":\"John\",\"Age\":30}"

Complex Examples

4. Full encoded email with body

Launch(
    "mailto:" & varManager.Email &
    "?subject=" & EncodeUrl("[Approval] " & Gallery1.Selected.Title) &
    "&body=" & EncodeUrl(
        "Record ID: " & Gallery1.Selected.ID & Char(10) &
        "Requested by: " & User().FullName & Char(10) &
        "Due: " & Text(Gallery1.Selected.DueDate, "dd MMM yyyy")
    )
)

5. JSON snapshot in audit log

Patch(AuditLog, Defaults(AuditLog), {
    Action:     "Update",
    RecordID:   Gallery1.Selected.ID,
    DataBefore: JSON(Gallery1.Selected, JSONFormat.IndentFour),
    ChangedBy:  User().Email,
    ChangedOn:  Now()
})

6. Build a Power Automate trigger URL with parameters

Launch(
    varFlowTriggerURL &
    "?customerID=" & EncodeUrl(Text(varCustomer.ID)) &
    "&action=" & EncodeUrl("SendWelcomeEmail") &
    "&language=" & EncodeUrl(varUserLanguage)
)

Best Practices

  • Validate inputs before using in write operations.
  • Combine with related functions for complete workflows.
  • Test with both empty and populated data sources.
  • Consider delegation when working with large data sets.
