Or if the cell contains the key: if key in str(cell): This will search only the first character of the cell if it's exactly the searched value.
#SEARCH FOR TEXT IN FILES PYTHON CODE#
If you need to perform partial match than you can try with Python code like: if str(cell) = key: The previous examples work with exact text matches for the cell value. In case of a match then we will replace the cell with the new values. Getting the number of rows and columns is done by:įinally we iterate and search for the values. In the file there are several sheets - we are interested in the one named - Test. The code above reads file: example1.xlsx from folder ~/Documents and then produces a new Excel file in the current working directory. Wb = openpyxl.load_workbook('/home/vanx/Documents/example1.xlsx')Ĭell = str(sheet.value) Difference is that only one module is used for reading and writing new Excel file: import openpyxlįrom import get_column_letter It can do the same as the previous example. Where new_workbook.save('example.xlsx') saves the data into file - example.xlsx Python and Excel - search and replace with openpyxlĪnother Python package exists and can be used - openpyxl. New_sheet.write(i, index, str(replacement.get(value))) This is the final part of the code: # iterate over the rowsĭata = nrows - number of rows in the selected sheet.ncols - number of columns in the selected sheet.The next step is to define replacement pairs like: Step 4: Search and replace a cell in xlsx fileįinally the code iterates over the rows and columns is controlled by: Step 3: Search and replace a cell in xlsx file New_sheet = new_workbook.add_sheet('Test') The second package - xlwt - will be used to write the data into new Excel file: new_workbook = xlwt.Workbook() Workbook = xlrd.open_workbook('/home/vanx/Documents/example1.xlsx') The first package reads the Excel file and a given sheet by name or index: import xlwt In this example we are going to use two Python packages: xlrd and xlwt. AĮasily extract information from Excel with Python and Pandas Python and Excel - search and replace with xlrd and xlwt We are going to search for 0 and 1 - and replace them with False and True. At the end a new Excel file is generated with the replaced values. We then use an xpath expression to extract all the ids in a list data structure. This is then passed to etree for parsing it into an xml tree. We open the xml file in binary mode and then read the entire contents. In this article you can find the exact cell(with packages like xlrd, xlwt and openpyxl) and partial cell match. The following python script prints all the customer ids present in the sample XML. If so, I'll show you the steps to search in Excel file - list of words and replace them.
