Variables

var (
	UTF8    = unicode.UTF8
	UTF8BOM = unicode.UTF8BOM
	GBK     = simplifiedchinese.GBK
	//UTF16 有很多种 参考 unicode包
	UTF16 = unicode.UTF16(unicode.LittleEndian, unicode.ExpectBOM)
)

常用文件编码 unicode.UTF8, unicode.UTF16(BigEndian, UseBOM), unicode.UTF16(BigEndian, IgnoreBOM), unicode.UTF16(LittleEndian, IgnoreBOM), 常用文件编码需要用

Types

type CsvReader

type CsvReader struct {
	FilePath string
	Comma    rune //csv 列分割符
	// contains filtered or unexported fields
}

func NewCsvReader

func NewCsvReader(csvFile string, comma rune) (*CsvReader, error)

comma 默认传 ','

func (*CsvReader) ReadAll

func (c *CsvReader) ReadAll(encoding encoding.Encoding) ([][]string, error)

func (*CsvReader) ReadAllJson

func (c *CsvReader) ReadAllJson(encoding encoding.Encoding) ([]map[string]string, error)

第一行作为字段名称，后续行数据转换为json数据一次性返回所有数据

func (*CsvReader) ReadGBKAll

func (c *CsvReader) ReadGBKAll() ([][]string, error)

func (*CsvReader) ReadGBKLine

func (c *CsvReader) ReadGBKLine(lineDataFunc func(record []string) error) error

func (*CsvReader) ReadLine

func (c *CsvReader) ReadLine(encoding encoding.Encoding, lineDataFunc func(record []string) error) error

func (*CsvReader) ReadLineJson

func (c *CsvReader) ReadLineJson(encoding encoding.Encoding, lineDataFunc func(record map[string]string) error) error

第一行作为字段名称，后续行数据转换为json数据,一行回调一个json数据

func (*CsvReader) ReadUTF16All

func (c *CsvReader) ReadUTF16All() ([][]string, error)

func (*CsvReader) ReadUTF16Line

func (c *CsvReader) ReadUTF16Line(lineDataFunc func(record []string) error) error

func (*CsvReader) ReadUTF8All

func (c *CsvReader) ReadUTF8All() ([][]string, error)

func (*CsvReader) ReadUTF8Line

func (c *CsvReader) ReadUTF8Line(lineDataFunc func(record []string) error) error

type CsvWriter

type CsvWriter struct {
	FilePath string
	Comma    rune //csv 列分割符
	// contains filtered or unexported fields
}

type XlsxRead

type XlsxRead struct {
	FilePath string
}

需要扩展按行读取文件

func NewReader

func NewReader(xlsxFile string) (*XlsxRead, error)

func (*XlsxRead) Read

func (r *XlsxRead) Read(fn func(n int, row []string) error) error

func (*XlsxRead) ReadBySheet

func (r *XlsxRead) ReadBySheet(sheet string, fn func(n int, row []string) error) error

func (*XlsxRead) ReadFile

func (r *XlsxRead) ReadFile(file string, fn func(n int, row []string) error) error

type XlsxWrite

type XlsxWrite struct {
	// contains filtered or unexported fields
}

扩展需要append to file 功能

func NewWriter
