Connector
Connects to a sheet your team already keeps, in a shared workspace or on a shared drive. It is granted read access to the tabs you choose and nothing wider, so it can open the sheet and cannot edit a cell.
Turn a spreadsheet into a board everyone reads
Reporting for teams that run on a spreadsheet
Toneinux connects to the spreadsheet your team keeps, reads the named ranges you point it at, and draws them as a board of panels that refreshes when the sheet changes. The sheet stays the sheet. Nobody exports, nobody rebuilds the Monday slide, and nobody copies a figure by hand.

What holds
Reads the sheet you already keep
No import and no template to fill in. Point the connector at a tab and it reads from there, on the schedule you set.
One board, shared by link
A board has one address inside your workspace. Send the link to a seat and there is nothing to install.
Read-only views for people who only look
A viewer sees the panels and the time of the last read, and cannot move, resize or remove a thing.
Not a database, and it never writes to your sheet
The connector holds a read scope only. Your sheet is the source of truth; the board is a way of reading it.
The panels
Six parts, and nothing hidden behind a tier. Every board in every workspace is built from the same six.
Connects to a sheet your team already keeps, in a shared workspace or on a shared drive. It is granted read access to the tabs you choose and nothing wider, so it can open the sheet and cannot edit a cell.
The unit the board reads. One named block of cells feeds one panel. Insert a row above it and the range moves with the block; rename it and the panel follows. Cell addresses are never used.
A figure for one value, a trend for a row or column of values, a table for a rectangular range, a note for a text cell. Each is drawn from exactly one range and shows its last read beneath it.
Every refresh stores the values it read. Pick a date on the board and each panel shows itself as it stood then, which settles the month-end argument about what the number was on the day.
A board is shared by link inside your workspace to people who hold a seat. Editors place panels; viewers read. There is no public link and no embed code, so a board cannot be pasted out of the company.
The connector re-reads on the interval you set and whenever someone presses refresh. A panel whose range could not be read is marked stale with the time of its last good read, never silently frozen.
How we work
Toneinux is a small software company in Tallinn. We make one tool: it reads a spreadsheet a team already maintains and draws the parts that matter as a board, arranged on one page and refreshed whenever the sheet changes. That is the whole product. We do not sell a database, a data warehouse or a consultancy, and we would rather say so on the first page than on the last call.
A job runs in a fixed order. It starts with your enquiry: a few lines about the sheet, who reads it and how often. We reply by email with times for a walkthrough, a call of about forty minutes on which we build a board in front of you, on a copy of your own sheet if you are willing to share one, or on a sample sheet if you are not. If the tool fits, we open a trial workspace, connect one sheet through a read-only connector and name the first ranges together. Your team then reads the board for a few weeks. Panels get added, moved and dropped; the sheet is never touched. At the end of the trial you either sign a seat agreement or close the workspace, and the trial data goes with it.
The sheet is the source of truth and the board is a way to read it, so the tool never writes back, not even a timestamp. A panel that cannot be read says so, with the time of its last good read, instead of showing an old figure as if it were fresh. Access is by seat and by link, and taking a seat away is one action. And we answer questions plainly, including the ones whose honest answer is that the tool is not for you.

Questions
Any spreadsheet a connector can reach with read access: a browser-based sheet in a shared workspace, or a spreadsheet file on a shared drive the connector can open. The board reads named ranges, so the sheet needs to allow naming a block of cells, which every mainstream spreadsheet does. If yours is unusual, say so in the enquiry and we will check it before the walkthrough rather than during it.
No. The connector is granted read access only, and the tool has no path that writes to a cell, a tab or a comment. It cannot add a timestamp, a helper column or a hidden tab. If a range is renamed or deleted in the sheet, the panel that read it is marked stale; the sheet itself is left exactly as your team left it.
People who hold a seat in your workspace, and only them. A board is shared by a link that opens for a signed-in seat; there is no public link. A seat is either an editor, who can place and move panels, or a viewer, who can only look. An owner sees who holds a seat and can take one away at any time.
If the file moves to another folder or a tab is renamed, the connector loses the sheet and every panel on the board shows a stale mark with its last good read. Point the connector at the new location and, because panels are bound to named ranges rather than to cell addresses, they carry on where they left off. If a named range itself is deleted, that one panel stays stale until the range is recreated or the panel is bound to another.
Yes, and we prefer it. After the walkthrough we open a trial workspace, you connect one sheet through a read-only connector, and your team reads a real board for a few weeks. If you would rather not share a sheet at first, the walkthrough runs on a sample sheet and the trial can follow when you are ready.
No. There is a trial workspace after the walkthrough, and after that a seat-based agreement that we quote by enquiry: the number of seats and the number of connected sheets set it. We do not publish a price list, because most of the questions worth asking are about the sheet, not about the seat count.
In a data centre inside the European Union. What is stored is small: the values read from your named ranges at each refresh, the layout of each board and the list of seats. The sheet itself stays where it is. The security and data page sets out what is kept, what is not, and what happens when a team leaves.
Next step
Bring one sheet. Leave with a board.
A walkthrough is a call on your own numbers, or on a sample sheet if you would rather not share one yet. You will see a board built from a real sheet in about forty minutes, and nothing is signed on the call.
