The CSV Template Engine generates custom text output from CSV data using a template-based approach. Instead of writing code to transform each row, you define a template pattern with placeholders that reference CSV columns, and the engine fills in the values for each row. This is useful for generating bulk emails, product descriptions, personalized documents, code files, or any text output that follows a consistent pattern. The template syntax uses double curly braces ({{column_name}}) to reference CSV columns, and supports conditional logic, loops, and text transformations. You paste your CSV data and template pattern into the tool, and it generates the complete output by applying the template to each row. All processing happens in your browser, making it safe for generating personalized content from sensitive datasets like customer lists, medical records, or financial data.

How to use the Template Engine tool

  1. Load your CSV data: Drag and drop your CSV file, choose a file from your file explorer, or paste CSV data directly into the paste area.
  2. Configure input settings: Select the CSV delimiter and toggle whether the first row is a header.
  3. Write a template: Define a template using column headers as placeholders: {{ColumnName}} or {{0}}. For example: Hello {{Name}}, welcome to {{City}}!
  4. Set row separator: Choose how rendered rows are separated: newline, double newline, comma, tab, or space.
  5. Render and export: Click the "Render Template" button to generate the output, then copy or download the result.

Frequently asked questions

What template syntax does the engine support?
The engine uses double curly braces ({{column_name}}) to reference CSV columns. It supports basic string interpolation and can process each row independently.
Can I generate bulk emails from a CSV?
Yes. Create a template with {{name}}, {{email}}, and other placeholders, and the engine will generate a personalized message for each row in the CSV.
Does the template engine support conditional logic?
The current version supports basic string interpolation. For conditional logic, you can use column-based template variations or combine with external scripting.
What output formats can I generate?
Any text-based format: HTML, Markdown, plain text, SQL, XML, JSON, code files, configuration files, or email templates. The engine produces raw text output.
Is there a row limit for template generation?
The engine processes all rows in the CSV. For very large datasets (10,000+ rows), the Web Worker ensures the browser stays responsive during generation.
