Converting boolean values to string format with Pandas

I have an Excel spreadsheet with a column formatted as "General" containing values like 10cm, 0, 1, TRUE, and FALSE. I am using Pandas to parse the data into a dataframe and then save it in an SQLite table. However, I want the values in this column to retain their original formats.

So far, I have used xl=pd.ExcelFile() to read the file and xl.parse() to extract the data. But when parsing, the FALSE value in the column is being converted to 0, which creates confusion with actual 0 values. The code snippet causing the issue is:

df=xl.parse(sheet_name=sheet,names=columns,skiprows=2)

The variable 'sheet' represents the given sheet name, while 'columns' is a list of column names.

Can anyone provide assistance in resolving this problem?

Answer №1

This is the method I used:

df = pd.read_excel('C:\\Users\\Downloads\\Practice\\Book1.xlsx',header=0,converters={'General':str})
df

Results:

General 10cm 0 1 True False

Answer №2

To define its type, you can utilize the dtype parameter. Give this a try:

df = pd.read_excel('file_path',sheet_name=sheet,skiprows=2,dtype={'General':object})

Answer №3

One way to prepare data for exporting to Excel is by converting the boolean values TRUE and FALSE to string objects, as demonstrated below:

pd['General'] = pd['General'].map({True: 'True', False: 'False'})

An alternative method with the same outcome is using the replace function:

pd['General'] = pd['General'].replace({True: 'True', False: 'False'})
