4. Text Functions in PowerApps – Complete Guide

Working with text is one of the most common tasks in PowerApps applications. Whether you are formatting user input, displaying dynamic content, or manipulating strings for data storage, text functions in PowerApps play a vital role.

PowerApps provides a wide range of text functions that help you format, search, replace, split, and join text values. In this guide, we’ll explore all the important text functions, their syntax, and real-world use cases.

---

🔹 1. Concatenate & Concat Functions

Used to join text strings together.

• Concatenate: Joins two or more text strings.

  Concatenate("Hello ", "World") 
  // Output: Hello World
  

• Concat: Joins values from a table into a single text string.Concat(Employees, Name, “, “)
  👉 If Employees table has:

  Name	Age
  John	30
  Emma	28
  Raj	35

  Output:
  John, Emma, Raj

📌 Use when you need to merge multiple strings or display a list of names, IDs, or values.

---

🔹 2. Len Function

Returns the length of a text string.

Len("PowerApps")  
// Output: 9

✅ Useful for validations like minimum/maximum character limits in input fields.

---

🔹 3. Left, Right, Mid Functions

Extract parts of a text string.

• Left:

  Left("PowerApps", 5)  
  // Output: Power
  

• Right:

  Right("PowerApps", 4)  
  // Output: Apps
  

• Mid:

  Mid("PowerApps", 2, 4)  
  // Output: ower
  

📌 Commonly used for extracting codes, prefixes, or suffixes.

---

🔹 4. Upper, Lower, Proper

Change text case.

• Upper(“powerapps”) → “POWERAPPS”
• Lower(“PowerApps”) → “powerapps”
• Proper(“power apps guide”) → “Power Apps Guide”

✅ Helpful in data standardization.

---

🔹 5. Trim & TrimEnds

Remove unwanted spaces.

• Trim → Removes extra spaces between words.

  Trim("   Power   Apps  ")  
  // Output: "Power Apps"
  

• TrimEnds → Removes leading & trailing spaces only.

  TrimEnds("   PowerApps   ")  
  // Output: "PowerApps"
  

---

🔹 6. Replace & Substitute

Used for text replacement.

• Replace: Replace based on position.

  Replace("PowerApps", 6, 4, "Platform")  
  // Output: PowerPlatform
  

• Substitute: Replace based on matching text.

  Substitute("PowerApps is cool", "cool", "awesome")  
  // Output: PowerApps is awesome
  

---

🔹 7. Find & Search

Locate text inside a string.

• Find (case-sensitive):

  Find("App", "PowerApps")  
  // Output: 6
  

• Search (case-insensitive):

  Search("app", "PowerApps")  
  // Output: 6
  

✅ Useful in validations, filtering, and keyword search.

---

🔹 8. StartsWith & EndsWith

Check if text starts/ends with certain characters.

StartsWith("PowerApps", "Power") // true  
EndsWith("PowerApps", "Apps")   // true  

📌 Helpful for validating codes, prefixes, or file extensions.

---

🔹 9. IsMatch Function

Checks if text matches a pattern using regular expressions.

IsMatch("abc123", "^[a-z]{3}[0-9]{3}$")  
// Output: true

✅ Great for validating email, phone number, or custom formats.

---

🔹 10. Text Function

Converts numbers, dates, and other values into text with formatting.

Text(1234.56, "$#,###.00")  
// Output: $1,234.56  

Text(Today(), "dd-mm-yyyy")  
// Output: 26-08-2025

📌 Crucial for display formatting.

---

🔹 11. Char Function

Returns a character by its ASCII/Unicode code.

Char(10) // Line break
Char(64) // @ symbol

✅ Useful for adding line breaks or special characters.

---

🔹 12. Value Function

Converts text to a number.

Value("123.45")  
// Output: 123.45 (Number)

📌 Important when working with numeric calculations on text fields.

6. Common Pitfalls and Best Practices – Text Functions in PowerApps

Pitfalls

• Using Concat() instead of Concatenate() for non-table inputs.
• Ignoring nulls and blanks, leading to runtime errors.
• Overusing nested text functions, reducing readability.

Best Practices

• Break down complex text logic using Set() or UpdateContext().
• Validate user inputs with regex (IsMatch()).
• Always Trim() before comparing strings.
• Use consistent casing (e.g., convert all usernames to lowercase).

Avoiding these pitfalls will make your use  more efficient and professional.
