About Convert CSV

Convert CSV is a free online platform that helps people work with structured data — converting between formats, editing spreadsheets in the browser, and downloading clean results without installing software or creating an account.

Our Mission

Data comes in dozens of formats — CSV, Excel, JSON, XML, YAML, SQL, HTML tables, bank statement files, and more. Most people just need to get their data into a spreadsheet, clean it up, and move on. They should not need to install Python, learn a command-line tool, or wait for a developer to write a one-off script.

Convert CSV exists to make everyday data conversion fast and accessible. Every tool runs in your browser, processes files locally, and produces a downloadable result you can verify before saving. No signup walls, no watermarks, no file retention.

What We Offer

Online Spreadsheet Editors

Upload CSV or Excel files and edit them in a browser-based spreadsheet grid. Fix values, remove blank rows, adjust column headers, and export the cleaned file — useful on its own or as a cleanup step before or after conversion.

Data Format Converters

More than 30 focused converters handle specific input-to-output transformations: JSON to CSV, XML to CSV, CSV to JSON, HTML tables to Excel, YAML to CSV, and many more. Each converter page includes format documentation, use cases, tips, and troubleshooting guidance.

Finance File Converters

Dedicated tools for OFX, QFX, QIF, IIF, and bank statement formats help bookkeepers and small business owners move transaction data between banks, accounting software, and spreadsheets.

Guides and Documentation

Our blog, format guides, FAQ, and documentation pages explain how each tool works, when to use it, and how to avoid common data quality problems. We write for real workflows, not search engines.

Privacy and Security

Your data stays on your device. Convert CSV processes files entirely in your browser using JavaScript — nothing is uploaded to our servers, stored in a database, or shared with third parties. When you close the tab, your data is gone. Read our Privacy Policy for full details.
