ECharts Parameter Formatter

This tool formats and canonicalizes ECharts parameter objects from user input or extracted configurations. It standardizes key ordering, normalizes value formats, and preserves nested functions when present, producing readable, production-ready configuration blocks. The process handles JSON and JavaScript object syntax, returning outputs suitable for direct inclusion in codebases or configuration pipelines.
Conceptually, it parses the input into a syntax tree, applies normalization rules (sort keys, collapse redundant whitespace, convert single-element arrays), and outputs a stable JSON or JS snippet. The formatter is deterministic, ensuring identical inputs produce identical outputs across runs, which aids version control and code reviews.
Who benefits: data engineers, frontend developers, BI teams integrating ECharts. Differentiators include support for nested option trees, multiple formatting styles, validation of common parameter structures, and deterministic output across runs. Core features include input validation, configurable formatting presets, delta/diff reporting, and safe handling of function code via stringification. Use cases span preparing design-system-ready charts, code reviews, and linting of ECharts configs to ensure consistency and maintainability.
