[Koha] Regarding Cataloging

[rocky bang]

Hi koha,

I have koha 3.08 and facing problems in cataloging modules.
I have cataloged records in koha using excel file being converted into marc
file and then uploaded in koha.
It was uploaded successfully and now i have to make some changes in the
Catalogued item and now i don't have the excel file which i have migrated
earlier into marc.
As editing single record one by one is a tedious job.
So is there any way to take back the excel file from koha with all the
fields which i have entered.

Thanks in advance.
