About this file tool

Edit spreadsheet cells and export CSV or XLSX. Verify formulas and styles before relying on the output.

Is Spreadsheet Editor free to use?

The local browser workflow can be used without an account. Some operations depend on document libraries or a separately installed engine. Check the download before relying on a converted document.

What happens to the original file?

Your source file is not overwritten. Local tools process it in the browser when supported; advanced server-powered operations are identified in the tool before you submit a document. Large file transfers require the sender and receiver to stay connected.

How to share files with MallowShare

Need to send photos, a large video, project files or documents to a group? MallowShare lets you share them in one temporary room instead of sending each person separate links.

⚡ 01 · START

Create a room

Choose a room name, set a password or use Quick Share. Rooms can last up to 10 minutes.

▦ 02 · CONNECT

Invite your people

Share a secure link or QR code. A valid QR invite lets participants join without retyping a password.

📁 03 · ENJOY

Share and download

Send photos, PDFs, videos, code and notes. Each person can select specific files or download an optional ZIP.

One room for every file type

Use MallowShare to transfer files between your phone, computer and friends' devices. Its browser-based peer-to-peer engine attempts direct transfers when connections allow. Large files depend on your devices and network, and the sender normally needs to remain online.

Frequently asked questions

Is it MallowShare or MelloShare?

The official spelling is MallowShare. People may type MelloShare or Mallow Share when searching; check the correct name and official website address before sharing a private invitation.

Is MallowShare free?

The sharing application can be used without signing up. Connection quality and file availability depend on network conditions and whether the sender stays online.

Can I share several files without creating a ZIP?

Yes. Recipients can choose individual files, use selected downloads or create a ZIP only if they want one.

Can people join with a QR code without entering a password?

Yes. A valid invitation QR contains a time-limited room access token, so scanning it can join directly. Keep QR invitations private.

Can I send a 2 GB movie?

Large file transfers are supported where browser and device capabilities allow. Speed is not guaranteed: connection quality, upload rate, relay availability and download support all matter.

Do files remain online forever?

No. MallowShare uses temporary room access. Peer-to-peer downloads usually require an active source, and people who already downloaded files retain their copies.

Spreadsheet Editor — common questions

Will Excel formulas still calculate?

Do not assume complex formulas survive; verify the exported workbook.

Can I edit a CSV?

CSV consists of rows and values, without native spreadsheet formatting.
