Example
Load
The csv file:
name, ID, number
name1, 1, 1.2
name2, 2, 2.3
name3, 3, 3.4
Your Go code:
type Demo struct { // A structure with tags
Name string `csv:"name"`
ID int `csv:"ID"`
Num float64 `csv:"number"`
}
tab := []Demo{} // Create the slice where to put the content
err := csvtag.LoadFromPath(
"file.csv", // Path of the csv file
&tab, // A pointer to the create slice
csvtag.CsvOptions{ // Load your csv with optional options
Separator: ';', // changes the values separator, default to ','
Header: []string{"name", "ID", "number"}, // specify custom headers
})
You can also load the data from an io.Reader with:
csvtag.LoadFromReader(youReader, &tab)
Or from a string with:
csvtag.LoadFromString(yourString, &tab)
Dump
Your Go code:
type Demo struct { // A structure with tags
Name string `csv:"name"`
ID int `csv:"ID"`
Num float64 `csv:"number"`
}
tab := []Demo{ // Create the slice where to put the content
Demo{
Name: "some name",
ID: 1,
Num: 42.5,
},
}
err := csvtag.DumpToFile(tab, "csv_file_name.csv")
You can also dump the data into an io.Writer with:
err := csvtag.DumpToWriter(tab, yourIOWriter)
Or dump to a string with:
str, err := csvtag.DumpToString(tab)
The csv file written:
name,ID,number
some name,1,42.5
