Appendix
Using CSV Files
You can save the data stored in the list variables, matrix variables or the Spreadsheet app as CSV files. You
can also load CSV files saved in the Storage Memory of the calculator into list or matrix variables, or into the
Spreadsheet app.
Important!
• Storage Memory (page 196)
• When saving and importing CSV files, take care to specify the delimiter and decimal point. For details,
see "Specifying the CSV File Import and Export Format (CSV Format)" (page
Import CSV File Requirements
A CSV file that has been output from the Calculate app, Statistics app, Spreadsheet app, or a CSV file
transferred from a computer to Storage Memory can be used for import. The following types of CSV files are
supported for import.
• A CSV file that uses the comma ( , ) or semi-colon ( ; ) as its delimiter, and the period ( . ) or comma ( , ) as
its decimal point. A CSV file that uses the tab as its delimiter is not supported.
• CR, LF and CRLF are supported for the line break code.
• When importing a CSV file to the calculator, if the data in Line 1 of each column of the file (or Line 1 of Column
1 of the file) is a character string enclosed with double quotation marks ( " ) or single quotation marks ( ' ),
Line 1 of all of the columns of the CSV file will be ignored, and data will be input starting from Line 2.
• A CSV file name can have up to eight single-byte characters.
Exporting to and Importing From a CSV File
Important!
• When saving matrix variables, list variables or the Spreadsheet app data to a CSV file, some data is
converted as described below.
- Fraction data: Converted to calculation line format (Example: 2 3 4 → =2+3/4)
- and π data: Converted to a decimal value (Example: 5 → 2.236067977)
• When a matrix or list variable is saved as a CSV file, the imaginary part of complex number data stored
by the variable is omitted. This means only the real part is saved.
• Attempting to import the following types of CSV files will result in an error.
- A CSV file containing data (expression or string) that cannot be converted. In this case, 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.
- A CSV file with more than 999 columns or 999 rows into a matrix variable.
A CSV file with more than 26 columns or 999 rows into a list variable or a spreadsheet.
In this case, an "Invalid Data Size" error will occur.
To save matrix variables to a CSV file (Calculate app)
1. Display the Calculate app's Matrix tab.
2. Highlight the matrix variable you want to save to a CSV file and then select T > [CSV] > [Save As].
• This displays a dialog you can use to select a folder to save the data.
3. Use the operation below to select the save destination folder.
To select this folder:
Root directory
is used as the memory area for saving and importing CSV files.
Perform this operation:
Highlight ROOT and then press O.
