+For accessing Wekan with Excel VBA, you can use Wekan REST API:
+
+https://github.com/wekan/wekan/wiki/REST-API
+
+For example, with using curl, you first login with admin credentials,
+by sending username and password to url.
+Change your server url etc details to below:
+
+```
+curl http://localhost:3000/users/login \
+-d "username=USER&password=PASSWORD"
+```
+=>
+```
+{
+ "id": "ABCDEFG123456",
+ "token": "AUTH-TOKEN",
+ "tokenExpires": "2018-07-15T14:23:18.313Z"
+}
+```
+Then you update card content by sending to card URL the new content:
+
+```
+curl -H "Authorization: Bearer AUTH-TOKEN" \
+   -H "Content-type:application/json" \
+   -X PUT \
+http://localhost:3000/api/boards/ABCDEFG123456/lists/ABCDEFG123456/cards/ABCDEFG123456 \
+-d '{ "title": "Card new title", "listId": "ABCDEFG123456", "description": "Card new description" }'
+```
+
+When using VBA, you can optionally:
+* Use direct VBA commands to send and receive from URLs
+* Download curl for Windows, and in VBA call curl.exe with those parameters, and get the result.
+
+You can also google search how you can use JSON format files in VBA,
+converting them to other formats etc. There could be something similar that
+exists in PHP, that JSON file can be converted to PHP array, and array items accessed
+individually, and array converted back to JSON.
+
+Current Wekan REST API does not yet cover access to all data that is in MongoDB.
+If you need that, REST API page also has link to Restheart, that adds REST API
+to MongoDB, so you can use all of MongoDB data directly with REST API.
+https://github.com/wekan/wekan/wiki/REST-API
+
+Wekan boards also have export JSON, where also attachments are included in JSON as
+base64 encoded files. To convert them back to files, you first get whole one board exported
+after authentication like this:
+
+```
+curl https://Bearer:APIKEY@ip-address/api/boards/BOARD-ID/export?authToken=#APIKEY > wekanboard.json
+```
+
+Then you read that JSON file with VBA, and get that part where in JSON is the base64 text
+of the file. Then you use VBA base64 function to convert it to binary, and write content to file.

+# CSV/TSC Import/Export
+
+There is [CSV/TSV pull request](https://github.com/wekan/wekan/pull/413), but it has been made
+a long time ago, it would need some work to add all the new tables, columns etc from
+MongoDB database, so that it would export everything correctly.
+
+Options are:
+
+a) Some developer could do that work and contribute that code to Wekan as
+new pull request to Wekan devel branch.
+
+b) Use [Commercial Support](https://wekan.team) and pay for the time to get it implemented.
