Excel to web app
Turn your Excel file into a web app your team actually uses
Upload the spreadsheet you already run the business on. Dosyon reads its structure -- columns, dates, statuses, repeated customer names -- and builds the first version of a working web app around it. You review what it proposes before anything goes live, and your original file is never touched.
The point where a spreadsheet stops working
A spreadsheet is an excellent tool for one person thinking. It becomes a liability the moment a second person needs to act on it. The failure is always the same shape: the file gets copied, the copies drift, and answering "which one is current?" turns into the job itself.
- The same record shows a different status in the office copy and the field copy.
- Anyone who can open the file can see and change everything in it.
- A broken formula propagates silently; nobody notices until a number is wrong downstream.
- There is no record of who changed what, so disputes cannot be settled.
- People outside the team -- customers, suppliers, contractors -- cannot contribute without being handed the file.
What you get from the file you upload
Dosyon is not a general-purpose no-code builder. It does not ask you to design an app; it reads the one you already built in a spreadsheet and proposes a structure. Where it is unsure, it asks instead of guessing.
- Table, form, Kanban and calendar views generated from the columns it recognises.
- Typed fields: dates, amounts, currencies and status values parsed rather than left as text.
- Relationships detected: repeated customer or supplier names become linked records instead of duplicated strings.
- Role-based access, including limiting people to only the records assigned to them.
- External intake links so customers or suppliers can submit information without joining your workspace -- submissions land in a review queue first.
- Export back to Excel (.xlsx) or CSV at any time. The data stays yours.
How it works
The file is analysed in your browser, so you can see the proposed structure before creating an account. Nothing is published until you approve the field mapping, and your original spreadsheet is left exactly as it was.
- Upload an .xlsx, .xlsm or .csv file.
- Review the detected fields, types and relationships; correct anything that is wrong.
- Publish, then invite your team and set who can see what.
- Keep evolving the app as the work changes -- new fields and views do not require rebuilding.
What changes in practice
| With a shared file | With Dosyon | |
|---|---|---|
| Source of truth | Several copies, none authoritative | One live record everyone works from |
| Permissions | All or nothing per file | Per member, per field, per assigned record |
| Mobile | Barely usable on a phone | Built for phone use in the field |
| Audit | Changes overwrite silently | Every change kept and timestamped |
| Outside contributors | Email the file and hope | Secure form link into a review queue |
Frequently asked questions
How do I convert an Excel file into a web app?
Upload the .xlsx or .csv file. Dosyon analyses the sheet structure, infers field types and relationships, and proposes a working app with table, form and Kanban views. You review and adjust the mapping, then publish it.
Do I need to know how to code or use a builder?
No. Unlike general-purpose no-code platforms, Dosyon does not start from a blank canvas. It starts from your existing file and proposes the structure, so there is no builder to learn before you see a result.
Does it change my original spreadsheet?
No. The upload is read-only. Dosyon creates a working copy; your original file stays exactly where it is, unchanged.
Can I control who sees which records?
Yes. Access is set per role, and you can restrict people to only the records assigned to them. Field-level visibility can also be limited.
Can people outside my team submit data?
Yes. You can send a secure form link to a customer or supplier without adding them to your workspace. What they submit enters a review queue and is only written to the record once you approve it.
Can I export my data back to Excel?
Yes, at any time, as Excel (.xlsx) or CSV. There is no lock-in on the data itself.
What file formats are supported?
Excel workbooks (.xlsx, .xlsm) and CSV files.
Is there a free trial?
You can upload a file and see the proposed app without creating an account. Publishing and team use start on the Starter plan, which includes a 14-day trial.
