Text Formatter to JSON

Purpose-built tool for engineers and analysts to turn raw text into machine-readable JSON with predictable structure and optional schema validation. It supports line-based parsing, schema-driven mappings, and JSONL output for streaming workloads. The transformation is deterministic, given the same inputs and options, making it suitable for automated pipelines and reproducible testing. The system preserves UTF-8 content and allows indentation control to fit developer preferences. This tool is particularly useful when log notes, configuration fragments, or experimental notes must be converted into precise JSON for ingestion or testing. Conceptually, the process treats input lines as potential fields, applies optional remapping or typing rules, and then serializes the result to JSON. It is valuable for teams that build APIs, data assets, or test data where consistency and auditability matter. The core value lies in reducing manual editing, minimizing parsing errors, and enabling rapid iteration on data schemas. Use cases include converting multiline notes to structured payloads, preparing sample API requests, and validating that free-form text conforms to a given schema. The tool supports both strict JSON and JSONL formats, depending on user needs, and provides clear error reporting when parsing or schema conformance fails.
