I am a data analyst (3): those things I had to say in the days when I was entangled with Quick BI

In the process of helping my husband use Quick BI to make reports, I encountered many problems along the way. Just like the development of the relationship between two people, from unfamiliar to familiar, sometimes crazy, sometimes surprised, summarize those The pit that has to be stepped on, I hope latecomers can bypass it.

1. The problem of csv file encoding is really crazy

BI tools that generally support local file uploading, such as AWS's QuickSight and Alibaba Cloud's Quick BI only support UTF-8 encoding, and garbled characters will appear after uploading non-UTF-8 files. People who use csv and excel to make reports have no technical background, and the coding conversion itself is very painful.

This problem also crashed me very much at the time. I saved excel as csv, and then uploaded it to Quick BI, and found that the data content displayed garbled characters, nnd, the original excel saved csv by default is not utf-8 (I guess it may be GBK), and even use sublime When I opened it, it was garbled. When I converted it to utf-8 in sublime, I found that it was still garbled. The developer GG said to use UltraEdit to convert it, but I downloaded UltraEdit on the mac, but it flashed back when I opened it, and it didn't work! What's going on? I feel like there are 3 more lines on my head, and countless crows fly over my head....

I have been tossing back and forth for a long time on this garbled problem before finally converting the encoding format, so I made a suggestion to Quick BI to ask if it can support some commonly used encoding methods.

What surprised me was that Quick BI already supports this function, and some common encoding methods can be automatically recognized, so I no longer need to find someone to help with encoding conversion, and it also supports excel upload, I even convert csv The operation can be saved, this speed, I have to give Quick BI a big compliment!

2. The problem that the map can't come out is really helpless

Generally, the data type of a two-dimensional table is either int or string. Provinces and cities are all string types. At first, I wanted to make a map chart, but I found out why the map could not be produced, and gave me a trend chart! what the hell is this
