28 free CSV and Excel tools. Nothing is ever uploaded.
This page is designed to help you find out whether CSVTidy is good and if it is the right choice for you.
CSVTidy is a free collection of 28 tools for cleaning and converting CSV and Excel files. It handles the usual spreadsheet mess — duplicate rows, inconsistent date formats, full names that need splitting, phone numbers in five different shapes, stray whitespace, broken encodings — plus format conversion to JSON, SQL, Markdown, HTML, XML and Excel, and structural work like splitting, merging, comparing and filtering files.
Everything runs client-side in your browser using JavaScript. Files are never uploaded, so there is no server to trust, no account to create, and no size limit imposed by an upload. It works on spreadsheets you would not be comfortable sending to a stranger's server.

Every other online CSV tool asks you to upload your file to their server. CSVTidy does the work in your browser — the file never leaves your machine. That means you can clean spreadsheets with customer data, salaries, or medical records without sending them to a stranger's server, and there's no file size limit imposed by an upload.
Three reasons: nothing is uploaded, there's no signup, and all 28 tools are real working transforms rather than previews that ask you to pay before you see the result. You can verify the privacy claim yourself — open your browser's network tab and watch that no request is made when you load a file.
Anyone who regularly receives messy spreadsheets from someone else: operations and finance people, analysts, CRM and marketing admins, and developers who need a quick CSV to JSON or SQL conversion without writing a script. It's aimed at people who know exactly what's wrong with their file and just want it fixed.
It started from repeatedly needing to clean the same kinds of messy exports — duplicate rows, five different date formats in one column, names that needed splitting — and being unwilling to upload files containing real customer data to a random converter site. Doing it in the browser removes that trade-off entirely.
Next.js and TypeScript, with Papa Parse for CSV parsing and SheetJS for Excel files. All processing runs client-side in the browser — there is no backend that touches user files.
