CSVTool.io
Free CSV tools that run entirely in your browser
CSVTool.io is a free toolkit of 62 browser-based CSV tools: viewer, editor, validator, dedupe, compare, split, repair with an auditable change trail, and converters to Excel, JSON, SQL and more. Everything runs locally in your browser with web workers - no uploads, no signup, no server. Your files never leave your device, and the viewer opens files too big for Excel.
Hi Product Hunt! I built CSVTool.io because every time I needed to quickly look at a CSV, the options were: upload it to a random site, wait for Excel to open, or write a throwaway script. These 62 tools run 100% in the browser - files never leave your device, and there is nothing to sign up for. The repair tool shows exactly what it changed and why, and the viewer opens files that make Excel cry. Would love your feedback on which tool to add next.
