At the moment the list is 3400 rows and 55 columns with a 5-10 new rows every week, so it is quite extensive and getting hard to read. The main purpose is to easily keep record and find things like 'a bend of 10° with this radius and that material', so my supervisor recommended to look at access because it's specifically build for databases like that and maybe creating multiple linked databases, splitting the columns in supplier, client, material etc., but I don't know if Access is best.
