i have some coins (similar bitcoin) in electrum mobile.
Are you saying that you are using Altcoins that have an "Electrum"-like mobile wallet?

You definitely should be able to export the private keys from the "electrum" wallet... although if it is truly based on the Bitcoin verions of Electrum mobile, it'll only export either the "12 word seed menmonic" or the Master Private Key (aka "xprv")...thank you for reading

Using either of those, you should be able to use tools that will allow you to generate the private keys for each address in your wallet... tools like:
Ian Coleman's BIP39 Mnemonic Converter: https://iancoleman.io/bip39/
Electrum specific version of the same tool: https://github.com/FarCanary/ElectrumSeedTester
Once you have the correct private keys, you'll be able to import them into the QT wallet fairly easily.
What coins, and what wallet specific are you using?
