GOOD TO KNOWA few things,
A few things,
before you begin.
Is Julretsu free to use?
Yes. The Julretsu license allows free personal, educational, and business use. Julretsu remains proprietary software; permission to use it does not transfer ownership. Read the full license.
Where does the download button take me?
It opens the Julretsu download folder on MediaFire. Choose the package for your operating system: Windows, Linux, or macOS. If it is an archive, extract it before opening the application and keep the supplied files together.
Can I use my existing Excel files?
Julretsu supports CSV and a subset of .xlsx features. Complex Excel workbooks may contain features that do not carry over. Keep your original file and check the format compatibility guide before importing important work.
Do I have to connect an AI account?
No. Spreadsheet editing and local calculations work without an AI connection. If you choose to use the assistant, it sends your request and worksheet context to your selected provider. You review its proposed changes before applying them.
