Build dynamic text with variables and templates. Generate code, emails, and reports instantly.
Create templates with variables. Build strings dynamically with real-time preview.
Real-time preview of your built string.
Text builders transform static templates into dynamic content using variable substitution. You create a template with placeholders, define values for those placeholders, and generate customized output instantly. This approach saves time when creating similar content with different details.
Variable substitution works by scanning your template for markers like {name} or {date}. When you build the string, these markers get replaced with actual values. Built-in variables handle common needs like current dates, timestamps, and random numbers. Custom variables let you define any values you need.
Template engines power email systems, code generators, report builders, and configuration file creators. Developers use them to generate boilerplate code. Marketers use them for personalized emails. Business teams use them for standardized reports with changing data points.
Real-time preview shows your output as you type. This immediate feedback helps you catch errors early and refine templates quickly. Statistics track variable usage, character counts, and word totals so you understand your output at a glance.
Formatting options control how your final string appears. Preserve line breaks for structured output. Trim extra spaces for compact text. Escape HTML for safe web display. These controls give you precise control over the generated content.
Repetition features let you generate multiple copies of your template with separators between them. This helps when creating lists, batch emails, or repeated code blocks. Set a count and separator, and the builder handles the rest.
Write your template with variable placeholders using {variable_name} syntax.
Add custom variables with names and values. Use built-in variables for common needs.
Set formatting preferences like line breaks, spacing, and HTML escaping.
Build your string and see real-time results with statistics and preview.
Email templates benefit from variable substitution. Create one template for welcome emails, then personalize each message with recipient names, dates, and account details. This approach scales better than writing individual emails.
Code generation uses templates to create boilerplate code. Define function templates with parameter placeholders. Generate multiple functions with different names and parameters. This speeds up development and ensures consistency.
Report generation combines templates with data. Create report structures with variable placeholders for metrics, dates, and summaries. Generate standardized reports with changing content automatically.
Configuration files use templates for environment-specific settings. Define one template with placeholders for database URLs, API keys, and feature flags. Generate configuration files for different environments quickly.
Answers to common questions about building dynamic strings with templates.
Use curly braces around variable names like {name} or {email}. When you build the string, these placeholders get replaced with the values you define. Variable names are case-sensitive.
The tool includes {date} for current date in YYYY-MM-DD format, {time} for current time in HH:MM:SS format, {timestamp} for Unix timestamp, {random} for random numbers between 1 and 1000, and {uuid} for unique identifiers.
If you enable "Keep Missing Variables", the placeholder stays in the output. If disabled, missing variables get replaced with empty strings. This helps you control how incomplete templates behave.
Yes. Set the repeat count to generate multiple copies of your template. Use the separator field to add text between repetitions. This helps when creating lists or batch content.
When enabled, HTML escaping converts special characters like < and > into safe HTML entities. This prevents HTML injection and makes your output safe for web display.
Yes. Text builders work well for generating code templates, function definitions, and configuration files. Define your code structure with variables, then generate multiple versions with different values.
