File Tools

File utilities, generators, and converters. 14 free online tools, no signup required. All tools run directly in your browser.

File Tools covers the quiet middle-manager chores that keep data moving between formats and systems. Data analysts convert a pasted spreadsheet snippet into clean rows with Spreadsheet TSV to JSON / SQL, or pull specific columns out of a huge CSV with CSV Column Extractor & Filter before the file becomes unwieldy. Developers confirm a download made it intact by computing its hash with File Hash, and package the fragile contents of a folder into one tidy archive with ZIP Creator. Anyone collaborating on documents compares two drafts side by side with the Side-by-Side Diff Viewer, while admins split oversized text exports into manageable parts with File Splitter. There is a place here for almost any file-shaped annoyance: formatting messy CSV, turning JSON into a table, generating a JSON Schema, even counting lines and measuring a file's true size. The processing is local, so the files you feed in are never uploaded, letting you work through sensitive spreadsheets and unreleased exports without a second thought. From quick one-offs to recurring pipeline steps, the tools reward the people who handle data all day. Everything is free, fast, and identical on desktop and mobile. Open the file tools the next time a CSV needs tidying, an export needs splitting, or a download needs a checksum.
