For Zaif files, there are two main reasons why they cannot be uploaded.
1. Uploading a ZIP file instead of CSV
Zaif transaction history files are downloaded in ZIP format (ZIP is a method of file compression).
Please check the password on the Zaif transaction history download page, extract (unzip) the ZIP, extract the CSV file, and upload it.
Reference for Windows users
Please install 7-Zip, and follow the below steps to unzip the file.
「7-Zip」https://sevenzip.osdn.jp/download.html
1) Right-click the file you want to unzip, and select "7-Zip" from the menu.
2) When the 7-ZIP menu appears, click "Extract files…" option.
3) Check which folder the unzipped file will be placed. If you want to the unzipped file to be placed in a different folder, click the "" button beside the "Extract to" field.
4) Click "OK".
2. Editing the extracted CSV
If you open the file after extracting the ZIP file, the character encoding and formatting may change and the upload may fail in some cases. Please upload the extracted CSV file as is.
