I used their CVS2QFX converter and it worked for me. I had to alter the imported data a bit: had to move fields around (payee and memo reversed) and had to drag copy them from a new checking account into my usual checking account but it worked. My bank said that after 90 days you had manually enter the data, and that is simply not true. But the trial version gets you all of 3 transactions, to go straight to the regular version. Their email support was surprisingly fast.
CSV2QFX review: What CSV2QFX does (imports your data into Quicken)
CSV2QFX converts data from CSV to QFX format and helps to import your data into Quicken without manual entry. When your bank is providing only CSV format or you have additional data in Excel, CSV2QFX will help you.
CSV2QFX reads your CSV file columns (the first line) and tries to understand the column content based on the column names. In the most cases, the CSV layout is recognized automatically and no manual mapping requires. Many banks are supported by default.
Some banks and credit card companies provide CSV files without the header. CSV2QFX can read those files and map them correctly for many cases as well (it can find the date column, the amount column, the currency column, the check column, the description column and so on). You can review how the CSV file is mapped and fix the mapping manually if required.
Quicken can QFX files when it is up to three years old. You can still import your CSV data into Quicken, but instead use CSV2QIF converter and import QIF files.
CSV2QFX is available on Windows and Mac. You may also convert files on Mac and import into Quicken on Windows, and convert to QFX on Windows and import into Quicken Essentials for Mac.
