k Transferring Data between a Spreadsheet and CSV Files
You can import the contents of a CSV file stored with this calculator or transferred from a
computer into a spreadsheet. You also can save the contents of a spreadsheet as a CSV file.
u To import the contents of a CSV file to a spreadsheet
1. Prepare the CSV file you want to import.
• See “Import CSV File Requirements” (page 3-18).
2. Press 1(FILE)5(CSV)1(LOAD).
• Pressing w in the next step will overwrite all of the data on the spreadsheet with the CSV
file data.
3. On the select file dialog box that appears, use f and c to move the highlighting to the
file you want to import and then press w.
• This imports the contents of the CSV file you specified to the spreadsheet.
Important!
• All blank data in the CSV file is imported as a blank cell.
• An error occurs if a CSV file contains even a single text string data item.
• If the CSV file includes data that cannot be converted, an error message will appear showing
the location in the CSV file (Example: row 2, column 3) where the data that cannot be
converted is located.
• Attempting to import a CSV file that has more than 26 columns or 999 rows will cause an
“Invalid Data Size” error.
u To save spreadsheet contents as a CSV file
1. If required, press 1(FILE)4(RECALCS) to recalculate the spreadsheet contents.
• Note that recalculation is not performed automatically when you save spreadsheet
contents to a CSV file. Be sure to perform recalculation if the spreadsheet contains a
formula, which starts with an equals symbol (=). See “Inputting a Formula into a Cell”
(page 9-10) for more information.
• Formulas are not saved to the CSV file. Only calculation results are saved.
• All ERROR cell data on the spreadsheet is saved as blank data.
