Transferring Data between a Spreadsheet and CSV Files

You can import the contents of a CSV file stored with the ClassPad 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" on page 134.
2. Tap [File] - [CSV] - [Open CSV].
• Tapping [Open] in the next step will overwrite all of the data on the spreadsheet with the CSV file data.
3. On the dialog box that appears, select the CSV file you want to import and then tap [Open].
Important!
Attempting to import a CSV file that has more than 64 columns or 999 rows will cause an "Invalid Data Size"
error.
u To save spreadsheet contents as a CSV file
1. If required, tap [File] - [Recalculate] 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
(=).
• 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.
2. Tap [File] - [CSV] - [Save CSV].
3. On the dialog box that appears, specify the export destination folder and then input a name for the export file.
4. Tap [Save].
u To specify the CSV file separator and decimal symbol
Tap [File] - [CSV] - [CSV Format] to display the CSV format setting screen. Next, perform the procedure from
step 2 under "To specify the CSV file separator and decimal symbol" (page 135).

Importing and Exporting Variable Values

You can import LIST (list), MAT (matrix), EXPR (expression), and STR (string) variables* into a spreadsheet.
LIST, MAT, and EXPR type variable in spreadsheet data also can be exported.
u To import the data assigned to a variable
1. In a spreadsheet, tap a single cell to specify it as the import destination of the variable data.
• If the variable you are importing is an EXPR or STR type, tapping the cell will input the variable data. For a
LIST or MAT type variable, data is input as shown in examples below when cell A1 is tapped.
LIST variable "{1,2,3}"
* For information about variable types, see "Main Memory Data Types" (page 28).
MAT variable "[[1,2][3,4]]" *
