Decode protobuf binary data (as hex or base64) to a human-readable field structure. Shows field numbers, wire types, and interpreted values without needing a .proto schema.

Convert SQL INSERT statements to a JSON array of objects. Paste one or multiple INSERT statements and get clean JSON ready for API testing, seeding, or migration.

Convert text to Unicode code points, HTML entities, or JS/Python escape sequences — and decode them back to text.

Convert hexadecimal strings to readable text and text back to hex encoding. Supports space-separated hex, 0x prefixes, continuous hex strings, and full UTF-8 output.

Decode base64-encoded JSON payloads and pretty-print the result with syntax highlighting. Supports standard and URL-safe base64 variants.

Convert INI configuration files and Java .properties files to JSON format instantly. Paste any INI file — php.ini, app.ini, Windows .ini — or a Java .properties file with dotted keys and get clean, structured JSON output. Supports section headers, inline comments, quoted values, boolean coercion (true/false/yes/no/on/off), numeric parsing, continuation lines, and Unicode escapes.

Validate TOML configuration file syntax and report errors with line numbers. Paste any TOML content — Cargo.toml, pyproject.toml, config.toml — and instantly see a green checkmark with key counts and structure stats, or a precise error message pointing to the exact line. Includes a collapsible JSON structure preview to confirm what was parsed.

Convert JSON objects to TOML configuration file format instantly. Nested objects become [table] sections, arrays of objects become [[array-of-tables]], and primitive arrays output as inline arrays. Optionally auto-detects ISO 8601 date strings and converts them to native TOML datetime values. Outputs clean, human-readable TOML ready for Cargo.toml, pyproject.toml, or any TOML-based config.

Convert TOML configuration files to JSON format instantly. Paste any TOML — Cargo.toml, pyproject.toml, config.toml — and get clean, pretty-printed JSON output. Supports all TOML types: strings (basic, literal, multi-line), integers (decimal, hex, octal, binary), floats, booleans, datetimes, arrays, inline tables, tables, and arrays of tables.

Extract HTML table markup and convert it to clean CSV format. Paste any HTML snippet or full page source — the tool finds the table, parses thead and tbody rows, handles colspan and rowspan merging gracefully, and outputs a properly quoted CSV ready to download or paste into a spreadsheet. When multiple tables are found, switch between them with a click.

Group and aggregate CSV data by one or more columns to create summary pivot views. Supports Count, Sum, Average, Min, and Max aggregations with multi-column grouping. Paste or upload any CSV, select group-by columns and aggregation type, and download the pivot summary as a new CSV file. Runs entirely in your browser.

Convert CSV data to formatted Markdown table syntax instantly. Supports quoted fields, embedded commas, and escaped quotes. Choose left, center, right, or auto alignment (auto right-aligns numeric columns). Output is properly padded and ready to paste into any Markdown document, README, or GitHub wiki.
