[~mayki] Can you please provide the stack trace from the logs? Also can you 
provide the file(s) in question if they are not sensitive otherwise you could 
dumb them down.

> Hello all,
> It seems all version greater 1.15.3 introduce a failure on the processor 
> *ConvertExcelToCSVProcessor* with this error :
> {code:java}
> Tried to allocate an array of length 101,695,141, but the maximum length for 
> this record type is 100,000,000. If the file is not corrupt or large, please 
> open an issue on bugzilla to request increasing the maximum allowable size 
> for this record type. As a temporary workaround, consider setting a higher 
> override value with IOUtils.setByteArrayMaxOverride() {code}
> I have tested with 2 differences instances nifi version 1.15.3 ==> Work: OK
> And since upgrade in 1.16, 1.17, 1.18 ==> same processsor *failed* with file 
> greater than 10MB.
> Could you help us to correct this bug ?
