Modern software development involves juggling disparate data formats, debugging compressed API payloads, formatting database queries, and converting epoch timestamps from server logs.
Switching between IDE plugins and ad-heavy third-party sites slows down your development cadence. Having lightweight, private, browser-based utilities at your fingertips keeps you in your coding flow.
In this guide, we review four essential developer utilities that streamline common data manipulation tasks.
1. SQL Query Formatting & Standardization
Long SQL queries written with nested subqueries, joins, and filters are difficult to debug and review during code reviews. Unformatted queries like:
select u.id,u.name,o.total from users u inner join orders o on u.id=o.user_id where o.status='paid' and o.created_at >= '2026-01-01' order by o.total desc;
can be converted into clean, readable SQL in one click:
SELECT
u.id,
u.name,
o.total
FROM users u
INNER JOIN orders o ON u.id = o.user_id
WHERE
o.status = 'paid'
AND o.created_at >= '2026-01-01'
ORDER BY
o.total DESC;
Our SQL Query Formatter supports uppercase and lowercase keyword toggles and works across PostgreSQL, MySQL, SQLite, Oracle, and MS SQL Server dialects.
2. XML Validation & Pretty Printing
Although JSON dominates modern REST APIs, XML remains central to SOAP web services, Android manifests, enterprise ERP feeds, and RSS/Sitemap architectures. Minified XML with unclosed tags can cause silent parsing failures.
The XML Formatter & Validator formats messy XML, highlights tag hierarchy mismatches with exact line numbers, and lets you minify XML payloads before sending them over the wire.
3. CSV to JSON & JSON to CSV Data Transformation
Tabular data exported from spreadsheets or financial tools arrives in CSV format, while web applications, React frontends, and NoSQL databases require structured JSON arrays.
Manually writing Python or Node conversion scripts for simple data imports is inefficient. The CSV to JSON Converter provides instant bidirectional conversion, auto-detects number and boolean primitives, supports custom delimiters (comma, semicolon, tab, pipe), and lets you download parsed datasets instantly.
4. Unix Epoch Timestamp Conversion
Backend servers and distributed databases log timestamps as Unix epoch numbers (the number of seconds or milliseconds since January 1, 1970 UTC). Translating a value like 1742000000 into a human-readable calendar date in local time or UTC is essential during database troubleshooting and API testing.
The Unix Timestamp Converter features a live ticking clock, bidirectional conversion, ISO 8601 string formatting, and relative time indicators ('2 hours ago') to simplify debugging.
