Documents & Data

Open, clean, merge, split, compare, and convert CSV, Excel, and Word files in your browser.

Open, clean, and move spreadsheet data without uploading it

Documents & Data on Haivix is a browser-local workbench for the files that usually force you into Excel, a converter site, or a scripting session. Open a CSV or workbook, inspect the rows, fix messy values, combine exports, split a file for an import limit, or compare two versions before you replace one with the other.

Every tool keeps the file in this tab. CSV parsing, Excel reading, DOCX conversion, cleaning, merging, splitting, and comparison use client-side libraries, so you can work with customer lists, finance exports, and internal reports without sending them to a server.
