DLM Data Format Converter
Convert Tables Between Multiple Formats
Transform your data instantly between CSV, JSON, HTML, Markdown, SQL, Word (DOCX), and more. Built for developers, data analysts, and content creators. Lightning fast with zero latency, all processing happens in your browser.
Key Features
Convert tabular data bidirectionally between CSV, JSON, HTML table, Markdown table, SQL INSERT statements, XML, YAML, Excel (XLSX), Word (DOCX), TSV, and LaTeX — covering every format used across development, data analysis, documentation, and content workflows without data loss or schema corruption.
All transformation logic runs as client-side JavaScript and WebAssembly — there is no file upload and no server round-trip. Conversion of even large files (10MB+) completes in under a second, with output appearing in the right-hand panel as you type or paste your source data.
Your data never leaves the browser. There are no backend servers, no file upload endpoints, no logging, and no data retention. This makes the tool safe for sensitive business data, internal database schemas, proprietary datasets, and any content that cannot leave a controlled environment.
Fully open-source and permanently free to use with no rate limits, no API keys, no accounts, and no premium tier. The architecture is inherently serverless because all computation happens on the client, meaning there's also nothing to go down, no service outages, and no maintenance windows.
