The routine described in step 1 allows to transfer and save the original data file from the measurement, independent of the file format and the content of the data. As FAIR data concepts require the availability of open and standardized data, step 1 needs to be followed by methods for the conversion of the data, in case they are not recorded in open and standardized file formats by the instrument. In our approach, the reading, processing and conversion of the original files is done by ChemConverter, a Python-based open source software, which is embedded into the workflows of Chemotion ELN . ChemConverter works according to a two-step routine: the first time data is obtained from a new device, the data is used to generate a profile that contains all necessary information for the conversion of the obtained file. This profile is stored in ChemConverter and is then used for all other data files coming from the device. This process of setting up a routine by an administrator of an ELN allows the users to apply this routine without further needs for configuration or adaptations. The routines of ChemConverter include both data and metadata conversion, as described in the following sections.
