Field formats can be tidied up when saving the library. That ensures your entries to have consistent formatting. In Library → Library properties, check Enable save actions. You can now select the actions to be carried out using the 2 drop-down menus located under the table. Each action is defined by:

• an entry field (upon which the action will be applied).

• the type of action to be carried out (such as HTML to LaTeX, which converts HTML code to LaTeX code, as described in the window).

A click on the "circular arrow" icon enables a set of recommended formatting actions (the set of actions will depend on your library type: BibTeX or BibLaTeX).​
