Data Transformation Tools

JSONPath Tester

The JSONPath Tester evaluates JSONPath expressions against any JSON in real time. Type $.store.books[?(@.price>40)] and see every matching value highlighted with its exact path. Supports dot notation, bracket notation, wildcards, array slices, recursive descent (..) and filter expressions. Ten example expressions are built in — click any to test against the sample immediately.

JSON to CSV Converter

The JSON to CSV Converter accepts any JSON array and produces a downloadable CSV file. It auto-detects column headers from object keys, handles nested objects by flattening them (a.b.c becomes a.b.c column), and supports comma, tab, semicolon and pipe delimiters. A table preview shows the first 20 rows before you download.

Markdown Table Generator

The Markdown Table Generator is a visual spreadsheet editor that outputs GitHub Flavored Markdown table syntax. Click headers to rename them, click cells to edit values, set per-column alignment (left, center, right) and add or remove rows and columns. A live preview renders the final table exactly as it will appear on GitHub or in your documentation.

Line Sorter and Deduplicator

The Line Sorter handles bulk text line operations: A-Z sort, Z-A sort, sort by length, reverse order, random shuffle, remove duplicate lines (case-sensitive or insensitive), trim whitespace, remove empty lines and add line numbers. Essential for processing CSV exports, log files, configuration lists and anything line-based.
