Field notes
Filecask organizes its converters into image, data, and finance sections rather than presenting one undifferentiated upload box. The visible menu includes dataset formats such as Parquet, SQL, XML, and RSS alongside accounting formats including QBO, OFX, QIF, and IIF. Its homepage states that images can reach 1GB, documents 100MB, and batches 50 files, with processing kept in the browser.
