Get numeric formatted text from a cell

[cognitivepedr0]

Hello,

I am not entirely sure this isn't already possible and I haven't spotted it, however I would need to be able to print out of a XLSX cell the same text which is rendered on the screen when it comes to numerical value, for instance (1,200) - at the moment I get what is called the "row" value, namely -1200 but I would need to the former string.

hi all - am I talking rubbish ? It seems to be that numbers value formatted as (123) do not get printed following the same formatting and what I get is the row value.

Is that actually correct or am I doing anything wrong ?

Thanks for your feedback. Which version of Excelize are you using, could you provide code or more details to reproduce this issue?

[cognitivepedr0]

I am following the tutorial and I am writing a simple script in an empty folder, no module defined.

go get github.com/xuri/excelize

You can find the code as a txt file
excel3.txt attachment

The
test.xlsx file is enough to show the issue:

./excel3 /tmp/test.xlsx 1
GetCellValue() -123134
A B
-123134 124214214
10000000 -1232121

But this is not how the numbers are formatted:

Hope this helps.

The Excelize not support to parse all the number formats of the cell, so you'll got the original value of the cell which same with the value you can see in the formula bar.

Is there a quick way for me to add the support for such format ?

I think we need to implement ECMA-376, ISO/IEC 29500 §18.8.31 number format strings lexer and parser to format values like Excel and other spreadsheet softwares.

not directly relevant to this issue, but pasting my workaround here for changing excel built in date formats to rfc3339. Might be useful for anyone hitting the issue I had (unexpected date formats)

Takes the output of f.GetRows and reformats anything it recognizes as a excel date format

func convertDates(f *excelize.File, sheetName string, rows [][]string) [][]string {
	for y := range rows {
		for x := range rows[y] {
			coords, _ := excelize.CoordinatesToCellName(x+1, y+1)
			style, err := f.GetCellStyle(sheetName, coords)
			if err != nil {
				_, _ = fmt.Println(err)
				continue
			}
			rows[y][x] = convertIfDate(f, style, rows[y][x])
		}
	}
	return rows
}

func convertIfDate(f *excelize.File, s int, v string) string {
	if s == 0 {
		return v
	}
	styleSheet := f.Styles
	if s >= len(styleSheet.CellXfs.Xf) {
		return v
	}
	var numFmtID int
	if styleSheet.CellXfs.Xf[s].NumFmtID != nil {
		numFmtID = *styleSheet.CellXfs.Xf[s].NumFmtID
	}
	var timeFormat string
	switch numFmtID {
	case 14:
		//"mm-dd-yy"
		timeFormat = "01-02-06"
	case 15:
		//"d-mmm-yy"
		timeFormat = "02-Jan-06"
	case 16:
		//"d-mmm"
		timeFormat = "02-Jan"
	case 17:
		//"mmm-yy"
		timeFormat = "Jan-06"
	case 22:
		//"m/d/yy h:mm"
		timeFormat = "1/2/06 15:04"
	default:
		return v
	}
	t, err := time.Parse(timeFormat, v)
	if err != nil {
		return v
	}
	return t.Format(time.RFC3339)
}

No error handling unless you consider spewing errors on to the console error handling.
When in doubt, return original value
And it only handles what I would consider easy date formats, only tested with 14 but works well enough for me
