Create reusable text templates with variable placeholders and fill them with custom values.
How to Use
- Choose your preferred variable delimiter style from the options at the top, or click "Custom" to define your own opening and closing delimiters
- Create your template by typing text and inserting variables using the selected delimiter syntax
- Variable names can contain letters, numbers, underscores, and hyphens (e.g., {{first_name}},{{order-123}})
- The tool automatically detects all unique variables in your template
- Fill in the values for each variable in the form that appears
- See the preview update in real-time as you fill in values
- Click "Copy Result" to copy the filled template to your clipboard
- You can use the same variable multiple times in your template - it will be replaced everywhere
💡 Pro Tips
- Use custom delimiters to match any existing template format (e.g., @@var@@, ~~var~~)
- Choose a delimiter style that matches your workflow (e.g., Dollar Brace for shell scripts)
- Click "Load Example" to see a sample email template with your selected delimiter
- Save your templates in a text file for reuse later
- Use descriptive variable names like {{customerName}} instead of {{x}}
- Leave variables empty to see where they appear in the template
- Switch delimiter styles anytime - just update your template text accordingly

Frequently Asked Questions
What is a text template engine?
A text template engine allows you to create reusable text templates with variable placeholders (like {{name}}, ${date}, [status], etc.) that can be filled with different values each time you use the template. This is useful for creating personalized emails, automated messages, code snippets, or any text that follows a consistent pattern but needs customizable parts.
What delimiter styles are supported?
The tool supports 6 popular delimiter styles: Double Curly Braces ({{variableName}}), Square Brackets ([variableName]), Angle Brackets (<variableName>), Percent Signs (%variableName%), Dollar Brace (${variableName}), and Hash Signs (#variableName#). Additionally, you can create custom delimiters by clicking the "Custom" button and specifying your own opening and closing characters (e.g., @@variableName@@, ~~variableName~~, etc.).
How do I use custom delimiters?
Click the "Custom" button in the delimiter style selector, then enter your preferred opening delimiter (e.g., @@) and closing delimiter (e.g., @@) in the input fields that appear. The tool will automatically detect variables using your custom delimiters. This is useful when working with templates that use non-standard delimiters or when you need to avoid conflicts with existing syntax in your content.
How do I create a template?
First, select your preferred delimiter style from the options at the top. Then write your text and insert placeholders using the selected delimiter syntax. For example, with curly braces: "Hello {{name}}, your appointment is on {{date}} at {{time}}." The tool will automatically detect all variables in your template and create input fields for each one.
Which delimiter style should I use?
Choose based on your use case: Double Curly Braces ({{...}}) are popular in templating engines like Handlebars and Mustache. Dollar Brace (${...}) is common in JavaScript template literals and shell scripts. Square Brackets ([...]) work well for simple replacement tasks. Percent Signs (%...%) are often used in configuration files. Angle Brackets (<...>) are familiar to XML/HTML users. Hash Signs (#...#) are good for avoiding conflicts with other syntax.
What placeholder syntax does this tool support?
The tool supports multiple delimiter syntaxes depending on your selection. All styles follow the same variable naming rules: variable names can contain letters, numbers, underscores, and hyphens. For example: {{firstName}}, [order_id], ${user-name}, %item1%. The tool will automatically extract all unique placeholders from your template based on the selected delimiter style.
Can I use the same variable multiple times in a template?
Yes! You can use the same variable placeholder multiple times throughout your template. When you fill in the value for that variable, it will be replaced in all locations where it appears. This is useful for creating templates where the same information (like a name or date) needs to appear in multiple places.
What are common use cases for text templates?
Text templates are widely used for: email templates with personalized greetings and details, automated customer notifications, code snippet generators, form letters, invoice templates, social media post templates, contract templates, documentation generators, and any scenario where you need to produce similar text with different specific details.
Can I save my templates for later use?
The tool processes everything in your browser and doesn't automatically save templates to the cloud. However, you can easily save your templates by copying the template text and saving it to a text file on your computer. You can then paste it back into the tool whenever you need to use it again.
Is there a limit to the number of variables I can use?
There is no hard limit on the number of variables you can use in a template. The tool will detect and create input fields for all unique placeholders in your template. However, for practical usability, it's recommended to keep templates focused and not overly complex.
Can I use special characters in variable names?
Variable names can contain letters (both uppercase and lowercase), numbers, underscores (_), and hyphens (-). They must start with a letter. Avoid using spaces or special characters like @, #, %, etc. Good examples: {{firstName}}, {{user_email}}, {{order-123}}. Invalid: {{first name}}, {{user@email}}.
How do I handle optional sections in templates?
While this tool focuses on simple variable substitution, you can handle optional sections by creating multiple template variations or by leaving certain variables empty when filling them out. If a variable is left empty, it will simply be replaced with an empty string in the final output.
Can I export or share my filled templates?
Yes! Once you've filled in all the variables, the preview section shows your completed text. You can use the "Copy Result" button to copy the filled template to your clipboard, then paste it into emails, documents, or any other application you need.
Does this tool support nested variables or complex logic?
This tool is designed for straightforward variable substitution and doesn't support nested variables, conditional logic, or loops. It focuses on simplicity and ease of use for common templating needs. For more complex templating requirements, you might need dedicated programming or scripting solutions.
Is my template data secure?
Yes, absolutely! All template processing happens entirely in your browser. No templates, variables, or filled content are ever sent to a server or stored anywhere. This ensures complete privacy and security for sensitive information like personal details, business data, or confidential content.
