Developer Data Format Converters — All in One Place
Modern software development involves working across a wide range of data serialization formats. An API might return JSON, your configuration might be TOML, your CI/CD pipeline uses YAML, a legacy system expects XML, and your stakeholders need everything in Excel or a nicely formatted HTML table. Converting between these formats manually is tedious and error-prone. These tools automate the conversion completely in your browser — no server round-trip, no data leakage, no account required.
CSV Conversion Tools
The CSV to Excel converter transforms any CSV file into a fully formatted XLSX workbook with auto-detected delimiters, configurable sheet names, and column width optimization. The Excel to CSV converter handles multi-sheet XLSX workbooks and lets you pick any sheet to export with your choice of delimiter. The CSV to SQL converter generates ready-to-run INSERT statements for MySQL, PostgreSQL, SQLite, and SQL Server with auto-detected column types. The SQL to CSV converter parses INSERT statements, MySQL tabular output, and PostgreSQL COPY output back into clean CSV. The CSV to HTML Table tool creates styled tables with Bootstrap, Tailwind, plain CSS, or bare HTML — with a live preview and sortable columns option. The CSV to Markdown converter produces GFM-compatible Markdown tables with per-column alignment and auto-column-width padding.
