Text to Structured Data Extractor – Offline Tool

Text to Structured Data Extractor is a lightweight HTML utility that converts unstructured text into structured datasets directly in your browser.

Designed for developers, analysts, researchers, and business users, it uses configurable regular-expression rules to extract useful information from text without requiring cloud services, API keys, or a backend.

Flexible Text Extraction

Define your own regex-based extraction rules, including named capture groups, to identify and organize information from raw text. Choose from multiple extraction modes depending on the structure of your source data.

Multiple Extraction Modes

Process text by matching indexes, creating one row per match, or extracting data line by line. The tool also supports bulk processing of multiple text files.

Export Structured Results

View extracted data in a table and export results as JSON or CSV. Bulk processing also supports ZIP archives for handling multiple files.

Save and Reuse Presets

Save extraction rules locally as presets and reuse them for recurring data-processing tasks.

Privacy-Focused Offline Processing

The utility is designed to run entirely in your browser. According to the product description, processing happens locally, so your text does not need to be uploaded to an external service.

Getting Started

Open the included index.html file in a supported modern browser, paste your text or load TXT files, configure the extraction rules, run the extraction, and export the results.

No server installation or API configuration is required.

Ideal for: Text data cleaning, bulk extraction, research workflows, log processing, and converting repetitive text formats into structured datasets.
