|
** Introduction
|
||
|
|
xlsx is a library to simplify reading and writing the XML format used
|
||
|
|
by recent version of Microsoft Excel in Go programs.
|
||
|
|
|
||
|
|
The support for writing XLSX files is currently extremely minimal. It
|
||
|
|
will expand slowly, but in the meantime patches are welcome!
|
||
|
|
|
||
|
|
** Full API docs
|
||
|
|
The full API docs can be viewed using go's built in documentation
|
||
|
|
tool, or online at [[http://godoc.org/github.com/tealeg/xlsx][godoc.org]].
|
||
|
|
|
||
|
|
** Basic Usage
|
||
|
|
*** Reading XLSX files
|
||
|
|
Here is a minimal example usage that will dump all cell data in a
|
||
|
|
given XLSX file. A more complete example of this kind of
|
||
|
|
functionality is contained in [[https://github.com/tealeg/xlsx2csv][the XLSX2CSV program]]:

||

#+BEGIN_SRC go
|
||
|
|
|
||
|
|
package main
|
||
|
|
|
||
|
|
import (
|
||
|
|
"fmt"
|
||
|
|
"github.com/tealeg/xlsx"
|
||
|
|
)
|
||
|
|
|
||
|
|
func main() {
|
||
|
|
excelFileName := "/home/tealeg/foo.xlsx"
|
||
|
|
xlFile, err := xlsx.OpenFile(excelFileName)
|
||
|
|
if err != nil {
|
||
|
|
...
|
||
|
|
}
|
||
|
|
for _, sheet := range xlFile.Sheets {
|
||
|
|
for _, row := range sheet.Rows {
|
||
|
|
for _, cell := range row.Cells {
|
||
|
|
text := cell.String()
|
||
|
|
fmt.Printf("%s\n", text)
|
||
|
|
}
|
||
|
|
}
|
||
|
|
}
|
||
|
|
}
|
||
|
|
|
||
|
|

|
|
|
||
|
|
Some additional information is available from the cell (for example,
|
||
|
|
style information). For more details see the godoc output for this
|
||
|
|
package.

||
|
|

|
*** Writing XLSX files
|
||
|
|
The following constitutes the bare minimum required to write an XLSX document.
|
||
|
|
|
||
|
|
#+BEGIN_SRC go
|
||
|
|
|
||
|
|
package main
|
||
|
|
|
||
|
|
import (
|
||
|
|
"fmt"
|
||
|
|
"github.com/tealeg/xlsx"
|
||
|
|
)
|
||
|
|
|
||
|
|
func main() {
|
||
|
|
var file *xlsx.File
|
||
|
|
var sheet *xlsx.Sheet
|
||
|
|
var row *xlsx.Row
|
||
|
|
var cell *xlsx.Cell
|
||
|
|
var err error
|
||
|
|
|
||
|
|
file = xlsx.NewFile()
|
||
|
|
sheet, err = file.AddSheet("Sheet1")
|
||
|
|
if err != nil {
|
||
|
|
fmt.Printf(err.Error())
|
||
|
|
}
|
||
|
|
row = sheet.AddRow()
|
||
|
|
cell = row.AddCell()
|
||
|
|
cell.Value = "I am a cell!"
|
||
|
|
err = file.Save("MyXLSXFile.xlsx")
|
||
|
|
if err != nil {
|
||
|
|
fmt.Printf(err.Error())
|
||
|
|
}
|
||
|
|
}
|
||
|
|
|

|

** Contributing
|
||
|
|
|
||

We're extremely happy to review pull requests. Please be patient, maintaining XLSX doesn't pay anyone's salary (to my knowledge).
