How safe is it to convert esp to esl?

[:bestgamerchina#1最好的中國]

I want to change some minor mods like armour or weapon type of mods, wich do not utilise any type of scripts, from esp to esl format. Never done that before.
That task creates two question I would like to know anwers for before I proceed.
Question number one. Can such mods cease to function in game, once I change their file type from esp to esl?
Question number two. Is it safe to change file type from esp to esl mid-game? Might that corrupt save or create problems with game immediately or later on?

General principles are don't eslify mods with scripts or those that make changes to world spaces. So on that front you have the right idea.

With regards to your second question some mods can theoretically be safely converted ie texture mods, but I would always say good modding practice, is to only do this before a new playthrough. Otherwise you are essentially asking for problems, of which there can be many and yes that includes save corruption

One final caveat is after converting a mod to esl any patches or the like that are dependent on the mod you have changed will "break". In particular this is the case where FormIds have changed and those said patches attempt to reference the original Formids. Something else to consider.

Using the Xedit tool is an easy way to eslify a file (you may well already know this)

Good luck!

NOTE: Any mod can be converted to an .esl that xEdit indicates can be - it has nothing to do with scripts or worldspace, but has to do with the size of the plugin file as regards the number of records it contains and whether it adds new cells to the game, which, under certain conditions, may result in a CTD.

I have learned something new. Thanks for the correction.
