Experiments

Paste raw or minified JSON to instantly format it with indentation, validate its structure, and catch syntax errors with descriptive messages.

Paste CSV data to get instant column statistics: inferred data types, row counts, null values, min/max/average for numeric columns, and top values for categorical ones.

Pick a base color and generate harmonious palettes: complementary, analogous, triadic, or monochromatic. Click any swatch to copy its hex value to the clipboard.

Analyze any text to get word count, unique words, sentence count, estimated reading time, and a ranked frequency bar chart of the most common words.

Write a regular expression and test it against any string in real-time. Highlights all matches inline and lists each matched value below.

A visual in-browser data pipeline: load sample JSON, then chain transform steps (filter rows, select columns, sort, rename fields) and inspect the output at each stage. Mimics ETL thinking without leaving the browser.

A lightweight API explorer. Pick from curated public API endpoints, fire a real GET request from the browser, and inspect the response status, headers, and formatted JSON body.
