ConvertCSV.com is a collection of online tools for converting CSV and Excel data to and from formats such as JSON, XML, SQL, YAML, KML, GeoJSON, HTML, Markdown and PDF. It also provides a CSV viewer and editor, a CSV validator, SQL querying and data extraction tools. The tools run on the client side, so data never leaves the computer.
VERNAM is a free, open-source file encryption tool that runs entirely in the browser. It encrypts any file with a passphrase using XChaCha20-Poly1305 and Argon2id, and no files or passwords are uploaded. It is published by PrivacyTools.io and offers an optional high security mode with heavier key derivation.
BackupPC is an open-source, enterprise-grade system that backs up Linux, Windows and macOS PCs and laptops to a server's disk. It includes a web interface for viewing logs and status, initiating and cancelling backups, and browsing and restoring files, plus data deduplication and compression. No client-side software is required. The latest release is 4.4.0, from June 20, 2020.
SpectrShare is a browser-based file sharing tool. Users drop files, start sharing, and send a unique link so files download directly between browsers. The site states there are no signups, uploads or cloud storage, and that closing the tab ends the share. It also lists built-in video streaming and file preview.
Recoll is a desktop document search application for Unix, Linux, Microsoft Windows and MacOS, built on the Xapian search engine library. It finds documents based on their contents as well as their file names and can search most document formats. The software is free on Linux, open source, and licensed under the GPL.
SDelete is a command-line Sysinternals utility that securely overwrites existing files and cleanses free space on a logical disk, including data in unallocated portions. It accepts wildcard characters in file or directory specifiers and implements the Department of Defense clearing and sanitizing standard DOD 5220.22-M. The tool securely deletes file data but not file names located in free disk space.
SKTimeStamp is a Windows shell extension that adds a tab to the Explorer properties dialog. The tab allows changing the date and time of files and folders. It requires Windows 10 22H2 or later.
