  1. Research Methods Group Importing text files in an MS Excel spreadsheet Wim Buysse – ICRAF-ILRI Research Methods Group August 2004

  2. Research Methods Group Importing text files: example • GPS

  3. Research Methods Group Importing text files: example • Data loggers, example weather station

  4. Research Methods Group Importing text files: example • Data loggers, example light intensity meter

  5. Research Methods Group Importing text files: example • Data loggers, example CO2 and temperature meter

  6. Research Methods Group Importing text files: example • Data loggers, example soil moisture logger

  7. Research Methods Group Importing text files: example • Data loggers, example rain gauge

  8. Research Methods Group Importing text files: example • Data loggers, example ICP mass spectrometer

  9. Research Methods Group Importing text files: example • Data loggers, example harvesters

  10. Research Methods Group Avoid entering manually • Reading data from device and next typing in spreadsheet = increasing chance of typing errors • Reading data from device on the field, writing on a piece of paper, travelling all the way back to the office and typing in spreadsheet (often some days later) = almost impossible not to make some mistake

  11. Research Methods Group Avoid entering manually • RULE = use cables and software to transfer data from device to computer • example = logging data from GPS onto a laptop

  12. Research Methods Group Avoid entering manually • Example of software (for logging GPS data)

  13. Research Methods Group Text data files • Result of logged data is quite often in ASCII text format

  14. Research Methods Group Importing in MS Excel 2000 • File => Open gives you the “Text Import Wizard”

  15. Research Methods Group Importing in MS Excel 2000 • In this example, fields to import are separated by commas. They are “delimited”

  16. Research Methods Group Importing in MS Excel 2000 • Choose the comma as delimiter in the second screen

  17. Research Methods Group Importing in MS Excel 2000 • More options in the third screen

  18. Research Methods Group Importing in MS Excel 2000 • The data are imported in cells of an Excel spreadsheet. Not a single typing error has been made!

  19. Research Methods Group Some functions • CONCATENATE() for merging text from several cells

  20. Research Methods Group Some functions • LEFT(); RIGHT() or MID() to extract a fixed number of characters from a specific position

  21. Research Methods Group Some functions • Result of =RIGHT(B2, 3) Is still text • Using the VALUE function turns it into figures

  22. Research Methods Group Some functions • It is possible to superpose a function on a function
