Save values of variables in a text file before closing document

[dbouilleux1]

Hello,
I would save in a macro called before leaving the document, a list of pairs (variable name, variable value) in a text file (outside the document, then).
I might as well load data from text file to restore the previously used values ​​of the variables.
The goal is to restore a configuration using a document (described using variables) after an update of this document.

Do you have any solutions?

Thank you for your answers.
Denis
