Python xlrd two methods for reading excel date types

This article mainly introduces two ways for Python xlrd to read the excel date type. This article also describes how to read a cell in excel by xlrd. For more information, see

There is an excle table that needs to be filtered and written to the database, but the cell of the date type is a number, so the solution is queried.

Basic code structure

The Code is as follows:

Data = xlrd. open_workbook (EXCEL_PATH)

Table = data. sheet_by_index (0)

Lines = table. nrows

Cols = table. ncols

Print u 'the total line is % s, cols is % s' % (lines, cols)

Read a cell:

The Code is as follows:

Table. cell (x, y). value

X: Line

Y: Column

Rows and columns start from 0

* Time type conversion: Convert the excel time to python time (two methods)

Excel: A Cell

The Code is as follows:

Xlrd. xldate_as_tuple (table. cell (). value, 0) # convert to the tuples

(2014, 7, 8, 0, 0, 0)

Xlrd. xldate. xldate_as_datetime (table. cell (). value, 1) # directly convert to datetime object

Datetime. datetime (2018, 7, 9, 0, 0)

Table. cell (2, 2). value # No Conversion

The Code is as follows:

# @ Param xldate The Excel number

# @ Param datemode 0: 1900-based, 1: 1904-based.

Xldate_as_tuple (xldate, datemode)

Input a cell of the date type will return a time structure consisting of tuples, you can set up a time type according to this tuples

Datemode has two options. Basically, we use the 1900-based timestamp.

The Code is as follows:


# Convert an Excel date/time number into a datetime. datetime object.


# @ Param xldate The Excel number

# @ Param datemode 0: 1900-based, 1: 1904-based.


# @ Return a datetime. datetime () object.


Def xldate_as_datetime (xldate, datemode)

The input parameter is the same as the preceding one, but the return value is of the datetime type, so you do not need to convert it yourself.

Of course, both functions have corresponding inverse functions, which convert the python type to the corresponding excle time type.
