Files tools

Tools for working with file names and data files such as CSV.

• Open a ZIP and extract files

  See what is inside a ZIP file and extract only the files you need, one at a time or together. Nothing to install, and the file is not uploaded.

• Batch rename files

  Add prefixes, suffixes, or sequence numbers, or replace text in file names, then save renamed copies as a ZIP. Your original files are not changed or deleted.

• Split CSV by rows

  Split a CSV file into several files with a set number of data rows each. The header row is added to every file, values stay unchanged, and you can save all files as a ZIP.

• Find duplicate files

  Find files with identical content in a folder or files you choose, and list them. Nothing is deleted or moved.

• Split and join files

  Split a large file into parts of a set size, then rebuild the original file on the receiving side. SHA-256 checks confirm the content matches.

• Compare two folders

  Compare an original folder with its copy and list missing files, files with different content, and matches. Nothing is copied or deleted.

• Combine CSV files into one

  Stack separate CSV files, such as monthly sales or member lists, into one table with matching columns. Values stay exactly as text.
