API & Addons

Valispace intends to be open to integration into various other tools.
This is how we imagine Valispace integrating with your engineering workflow:

Valispace Engineering Tool Integration

For this vision to become reality, Valispace offers a series of Addons and encourages you, to build additional ones yourself.


Most of the data stored in the Valispace database is accessible in machine readable (.json) format through a REST-API. You can find it in yourdeployment.valispace.com/rest/ (e.g. here in our demo deployment)

The REST API is very powerful and gives you direct read/write access to your data. However with great power comes great responsibility. In case you would like to write your own application which can interface to Valispace, don't hesitate to contact us to support you.

However we have already built some addons for your convenience:

MS Word Addon

The MS Word Addon lets you insert values from your Valispace deployment into your document as a field and let's you refresh them with the newest values at any time.
Valispace MS Word Ribbon

With Add Vali you can start typing to use the auto-complete function or select a vali from the dropdown:
Valispace MS Word Dropdown

With Refresh all Valis all values which have been inserted with this plugin are refreshed with the newest value.

Don't worry. When you give your Word Document to another person who does not have the plugin or access to your Valispace Deployment, all values will still be available in the document.

Download and installation

Download it here (v1.1) and install it by copying this file into the following folder: %APPDATA%/Microsoft/Word/STARTUP.
When you start MS Word, a new ribbon will appear: Vali-Tools. Fill in your user credentials using the ValiAddon Settingsbutton:

Remember to use https:// in the URL if you want the connection to be securely encrypted.

MS Excel Addon

The MS Excel Addon lets you exchange data bi-directionally between your Excel Worksheet and your Valispace deployment.

Excel Addon Menu

(Pull) Valis

By clicking on Add Vali in the ValiSpace Ribbon, you can select a Vali which you would like to reference in the cell which is selected. It will then be inserted.

By clicking on Refresh Valis in the ValiSpace Ribbon, all of your cells which reference (Pull) Valis in your workbook will be updated to the newest value from your Valispace Deployment.

Push Valis

Select a cell in your workbook, for which you want to recurrently upload its value to your Valispace deployment. Then click Add Push Vali to connect it to a Vali which you can select from the list.

Whenever you click Push Valis in the ValiSpace Ribbon, all Push Valis will be pushed to your Valispace deployment. You will receive a message with all performed updates.

Download and installation

1) Download it here (v1.1) and store it to a folder of your choice.
2) Open Excel, click on the main menu (or File in newer Excel versions) then Options --> Add-Ins --> Excel-Addins: Go...
3) Click Browse and select the .xlam file, select it with a check-box and click OK
4) A new Ribbon called Valispace should have appeared in the top main menu.
5) To prevent the need to re-do the same steps every time you start Excel, you will have to add the folder containing the Add-In to your "Trusted File Locations". To do this, click on File --> Options --> Trust Center --> Trust Center Settings... --> Trusted Locations --> Add new location... --> Browse and add the folder where you stored the Addon.
6) To setup Valispace, in the new ValiSpace Ribbon, select Settings and insert your deployment's URL (e.g. https://yourdeployment.valispace.com), your username and password and confirm with Save

MATLAB Toolbox

The Matlab Toolbox lets you read from and write to your Valispace deployment directly from your Matlab simulations.

Example Usage:

% 1) Valispace Login

% 2) optional: pull all Valis for faster access or access via name

% 3a) get Vali as a struct
3a) ValispaceGetVali("MySat.Mass")

% 3b) get value
3b) ValispaceGetValue("MySat.Mass")

% 4) push value to Valispace

% get matrix values from matrix ID
5)  ValispaceGetMatrix(217)

% push matrix values
6)  ValispacePushMatrix(217,[2,3;4,5])                                  

Please note: Until you run clear all the all ValispaceGetVali() and ValispaceGetValue() will use the cached values from your last ValispacePull() call.

ValispaceGetVali() / ValispaceGetValue() / ValispacePushValue() work with the argument as a string (name) or integer (id) i.e. ValispaceGetValue("MySat.Mass") and ValispaceGetValue(217).
When using these functions with an integer id, step 2) can be skipped. In this case the WebInterface will be accessed with every individual call.

Both ValispacePushValue() and ValispacePushMatrix() can also push formulas (e.g. $MySat.Mass*5) instead of values

Download and installation

Download it here (v1.2) and install the toolbox via double-click. You can then activate it by clicking the Valispace Toolbox Icon in your Apps Ribbon inside Matlab.

The Matlab plugin is tested with Matlab version R2017a.
