Do I keep my data?
Yes. The app imports your rows from Excel or CSV, and you can export them back to Excel whenever you want.
Turn an Excel spreadsheet into a desktop app
Describe what your spreadsheet keeps and what people do with it, and Ningal writes a Windows program that does the same with forms, search and reports. You import your current data from Excel, and everyone works in the app instead of the file.
Why a shared spreadsheet breaks
When several people edit the same file, someone overwrites a column, sorts half a table or saves an old copy on top of the new one. Nobody knows who changed what, and the file has no screens: everyone sees every cell.
What it looks like as an app
This example does the job of the contacts and sales sheet many teams share:
- Companies, contacts and deals, each with its own form instead of a row of cells.
- A pipeline board where deals are dragged between stages.
- Calls, meetings and tasks with due dates, and a "My day" view for each person.
- History on every record: who created or changed it, and when.
- Several people work from a shared folder, and nobody silently overwrites someone else's changes.
- Import contacts from Excel or CSV, and export any list to Excel.
Team CRM
Companies, contacts and a deal pipeline that the whole office shares from a network folder, with activities, a daily task list and a history of every change.

In your description, list the columns of your sheet, what each person needs to see and do, and ask for "Import from Excel" so you can bring the data you already have.
Read the full guideBefore you rely on it
- It runs on Windows 10 or 11 (64-bit) and on Ubuntu 24.04 or later. It is not a website or a phone app.
- Your data is kept in a database file inside the app's folder. Back up that folder regularly.
- If you ask for shared use in the description, several people can work with it from a shared network folder. Do not put the app's folder in OneDrive, Dropbox or Google Drive, which can damage the database.
- Try it with a copy of your data before you use it every day or share it with your team.
Questions
Do I need Excel installed?
No. The app reads and writes Excel files by itself.
Can my whole team use it?
Yes, from a shared network folder. Each person is identified by their Windows user name.
Do I need to know how to program?
No. You describe what the app does in your own words, in any language, and Ningal writes and packages the program.
Can I change the app later?
Yes. Describe the change in the editor, download it again and copy the new files over the old ones in the app's folder. Your data is in that folder, so it stays.
How much does it cost?
The free plan is enough to build and download your first app. Paid plans give you more apps and more AI usage each month.
