Text Batch Generator

Text Batch Generator is a template-based tool for producing large amounts of text automatically. Mark the changing parts of a line with curly-brace placeholders, assign a rule to each one, and the tool enumerates every result for you. Multiple placeholders are combined automatically, so a single template can expand into hundreds or thousands of unique lines.

Key Features

• Eight placeholder types: keep as is, number sequence, letter sequence, custom characters, date sequence, arithmetic progression, geometric progression, and custom list.
• Numbers and sequences: set a start value, end value and step, and pad to a fixed length; arithmetic and geometric series support first term, step or ratio, and count.
• Letters and characters: generate letter ranges with a skip value in uppercase, lowercase or both; custom characters can include digits, uppercase letters, lowercase letters and extra symbols at a chosen length.
• Date sequences: start from a chosen date and step forward by days or months, with formats such as YYYY-MM-DD, YYYY/MM/DD and YYYYMMDD.
• Custom list: type one candidate per line and use it directly as the placeholder source.
• Multi-variable combinations: all placeholders in one template are crossed automatically, with the expected line count shown before generating.
• Live preview and export: each placeholder previews the values it will produce, and results can be copied, downloaded as TXT, or exported to Excel.

Use Cases

• Bulk generation of filenames, serial numbers, IDs and batch codes.
• Building test data, sample text and placeholder content.
• Creating numbered lists, code combinations and sequential labels.
• Producing date-based report or log names in batches.

How to Use

1. Write your text in the template box and mark the changing parts with curly braces, for example photo-{no}-{letter}.png.
2. Choose a type for each detected placeholder and fill in its parameters (range, step, length, etc.).
3. Set the maximum number of lines, check the live count and preview, then click Generate.
4. Copy the result, download it as TXT, or export it to Excel.

FAQ

Q: How are multiple placeholders combined?

A: Each placeholder produces its own set of candidate values, and the tool crosses them together to generate every possible line, showing the expected count before generating.

Q: Can I save or export the results?

A: Yes. Results can be copied with one click, downloaded as a TXT file, or exported to an Excel spreadsheet for further editing.

Q: Are my template and settings saved?

A: The tool remembers the last template and parameters locally in your browser, so they are restored automatically the next time you open it.

Q: Is my content uploaded to a server?

A: No. Generation runs entirely in your browser, so your template and text never need to be uploaded.
