To String

Converts a boolean value to its string representation ("true" or "false"), making it suitable for logging, display, reporting, or string-based operations in RPA flows.

Common Properties

Name - The custom name of the node.
Color - The custom color of the node.
Delay Before (sec) - Waits in seconds before executing the node.
Delay After (sec) - Waits in seconds after executing node.
Continue On Error - Automation will continue regardless of any error. The default value is false.

info

If the ContinueOnError property is true, no error is caught when the project is executed, even if a Catch node is used.

Inputs

Bool Value - The boolean value to convert to a string. This can be:
- A direct boolean value (true/false)
- A variable containing a boolean value
- A JavaScript expression that evaluates to a boolean
- An AI-generated boolean value
- The result from a previous boolean operation or assignment

Output

String - The string representation of the boolean value, stored in the Message scope with the name str. The output will be exactly "true" or "false" (lowercase).

How It Works

When executed, the ToString node:

Retrieves the boolean value from the input
Converts it to its string representation using Go's standard boolean formatting
Stores the result as a string in the output variable

Conversion Table:

Input Boolean	Output String
`true`	`"true"`
`false`	`"false"`

Use Cases

1. Logging and Debugging

Convert boolean flags to strings for inclusion in log messages:

// After ToString node
log.info("Validation result: " + msg.str);
// Output: "Validation result: true"

2. Report Generation

Include boolean status in reports or notifications:

// After ToString node
msg.reportLine = "Processing completed: " + msg.str;
// Result: "Processing completed: false"

3. Email Notifications

Format boolean values for human-readable email content:

// After ToString node
msg.emailBody = "Account active: " + msg.str;
// Sends: "Account active: true"

4. String Concatenation

Combine boolean values with other strings:

// After ToString node
msg.status = "Feature enabled: " + msg.str + ", version: 2.0";
// Result: "Feature enabled: true, version: 2.0"

5. CSV/Excel Export

Prepare boolean data for export to CSV or Excel files:

// After ToString node
msg.csvRow = msg.name + "," + msg.str + "," + msg.date;
// Result: "John Doe,true,2024-01-15"

6. API Requests

Convert boolean values to strings for APIs that expect string parameters:

// After ToString node
msg.queryParams = "?active=" + msg.str + "&verified=true";
// Result: "?active=false&verified=true"

Examples

Example 1: Simple Conversion

Convert a validation result to string:

Configuration:

Bool Value: true
Output: msg.str = "true"

Example 2: Logging Validation Status

Convert a validation result and use it in a log message:

Configuration:

Bool Value: ${msg.validationPassed}
Output: msg.str (contains "true" or "false")
Usage: Send to Log node with message: Validation status: ${msg.str}

Example 3: Building Report Data

Prepare boolean flags for a status report:

Flow:

Check system status (result: true)
ToString node converts to "true"
Concatenate: "System operational: " + msg.str
Result: "System operational: true"

Example 4: CSV Row Creation

Create a CSV row with boolean data:

Configuration:

Bool Value: ${msg.isProcessed}
Output: msg.str

Next Node: String Concat node

${msg.recordId},${msg.recordName},${msg.str},${msg.timestamp}

Result: "12345,Sample Record,true,2024-01-15 10:30:00"

Example 5: Conditional Message Formatting

Format different messages based on boolean state:

Flow:

Operation node checks permissions (result in msg.hasAccess)
ToString converts msg.hasAccess to string
Switch node checks the original boolean
Build message using string: "Access granted: " + msg.str

Example 6: API Integration

Prepare boolean parameters for an API call:

Configuration:

Bool Value: ${msg.autoRenew}
Output: msg.str

Usage in HTTP Request:

URL: https://api.example.com/subscription?auto_renew=${msg.str}
Result: https://api.example.com/subscription?auto_renew=true

Tips for Effective Use

Use for Human-Readable Output
- Convert boolean values before displaying them to users
- Include in email notifications, reports, and UI messages
Consistent Formatting
- The output is always lowercase ("true" or "false")
- If you need different formatting (TRUE, Yes/No, 1/0), use additional string manipulation
Combine with String Operations
- Use string concatenation nodes to build complete messages
- Leverage template literals for more complex string building
Performance Consideration
- This is a lightweight operation with minimal performance impact
- Safe to use in high-frequency loops
Naming Convention
- Change the output variable name to be more descriptive
- Example: statusText, resultString, flagDescription

Common Errors and Solutions

Error: "Bool Value is undefined"

Cause: The input boolean value hasn't been set or the variable doesn't exist.

Solution:

Ensure a previous node sets the boolean value
Check variable names and scopes
Verify the boolean value is available in the message context

Error: "Type mismatch"

Cause: The input value is not a boolean type.

Solution:

Convert to boolean first: Use a JavaScript expression like ${!!msg.value}
Use comparison to get boolean: ${msg.count > 0}
Verify the source node outputs a boolean

Unexpected Output Format

Issue: Need "Yes/No" or "1/0" instead of "true/false".

Solution:

After ToString, use a String Replace or Function node to convert:

// Using a Function node:
if (msg.boolValue) {
  msg.customStr = "Yes";
} else {
  msg.customStr = "No";
}

Case Sensitivity Issues

Issue: Need uppercase "TRUE" or "FALSE".

Solution:

Use a String operation after ToString to convert to uppercase:

msg.upperStr = msg.str.toUpperCase();
// Result: "TRUE" or "FALSE"

Alternative Formatting Options

While ToString always outputs lowercase "true" or "false", you can easily transform the output:

Convert to Yes/No

// After ToString node, in a JavaScript node:
msg.yesNo = (msg.str === "true") ? "Yes" : "No";

Convert to 1/0

// After ToString node, in a JavaScript node:
msg.numeric = (msg.str === "true") ? "1" : "0";

Convert to Custom Labels

// After ToString node, in a JavaScript node:
msg.status = (msg.str === "true") ? "Enabled" : "Disabled";
// or
msg.status = (msg.str === "true") ? "Active" : "Inactive";
// or
msg.status = (msg.str === "true") ? "Success" : "Failed";

Uppercase Output

// After ToString node, in a JavaScript node:
msg.upperStr = msg.str.toUpperCase();
// Result: "TRUE" or "FALSE"

Best Practices

Use When Needed - Only convert to string when actually needed for string operations
Name Descriptively - Use clear output variable names that indicate the content
Consider Alternatives - For custom formatting, consider using a Function node or JavaScript directly
Preserve Original - Keep the original boolean value if you need it for logic operations
Document Purpose - Use the node name to indicate why you're converting to string
Chain Operations - Combine with other string nodes for complex formatting needs

Performance Considerations

ToString is a very fast operation with negligible performance impact
Safe to use in high-frequency loops and batch processing
No memory overhead - output strings are small fixed-size values
Thread-safe and suitable for concurrent flows

Integration Examples

With Log Node

// After ToString
"Validation completed: " + msg.str

With Email Node

// Email body template
Dear User,

Your account status:
- Active: ${msg.activeStr}
- Verified: ${msg.verifiedStr}
- Subscribed: ${msg.subscribedStr}

With Database Insert

// Prepare data for database
{
  user_id: msg.userId,
  is_active: msg.str,  // "true" or "false" as string
  timestamp: msg.timestamp
}

With CSV Writer

// CSV header: Name,Email,Active,Verified
// CSV row:
${msg.name},${msg.email},${msg.activeStr},${msg.verifiedStr}

Assign - Assign boolean values that can then be converted to strings
Operation - Perform logical operations before converting results to strings
String Concat - Combine the string output with other strings
Log - Use the string output in log messages
HTTP Request - Include string-formatted boolean values in API calls
Email - Include boolean status in email notifications
CSV Writer - Export boolean data as strings to CSV files
