CSV CleanerClean CSV files in your browser: trim cells, remove empty and duplicate rows, change the delimiter and preview the table before downloading.
File Utilities
General-purpose helpers for any kind of file. See a file’s real type from its signature bytes, bundle several files into a ZIP, convert small files to Base64 data URIs, and verify downloads with SHA checksums. Files are read with the browser’s File API and are never uploaded.
CSV ↔ JSON ConverterConvert CSV to JSON (array of objects or arrays) and JSON back to CSV.
File Size ConverterConvert file sizes between bytes, kilobytes, megabytes, gigabytes and terabytes in both decimal (1000) and binary (1024) units — or drop a file to see its exact size.
File Checksum (SHA-256)Calculate SHA-256, SHA-384, SHA-512 and SHA-1 checksums of a file in your browser and compare them with the hash published by the download site.
File Type & Info CheckerFind out what a file really is.
Create ZIP FileCombine several files into one ZIP archive in your browser.
Open ZIP FileLook inside a ZIP archive and download individual files without installing anything.
File to Data URIConvert an image, font or any small file into a Base64 data URI, with ready-to-paste CSS and HTML snippets and a size warning when inlining is a bad idea.
