hcxtools and cap2hccapx (two good friends)
If you are interested in wpa / wpa2 only, you can savely use cap2hccapx (https://github.com/hashcat/hashcat-utils) or the online converter (https://hashcat.net/cap2hccapx/) to convert hcxtools caps. cap2hccapx knows all about the features of hcxtools and will convert this cap to hccapx.
cap2hccapx also knows all about hcxtools beacons and proberesponses and prioritized association / re-associationrequests (https://github.com/hashcat/hashcat-utils/issues/27).
It is also possible to convert hccapx files (from cap2hccapx) back to a cap file, as cap2hccapx writes only message pairs which can be converted back (https://github.com/hashcat/hashcat-utils/issues/32).
cap2hccapx is also able to handle "big data" caps captured by hcxtools (https://github.com/hashcat/hashcat-utils/issues/28).
