Why CSV files open in one column
Excel splits a CSV using the list separator from your regional settings. In many European and Latin American locales that separator is a semicolon, because the comma is the decimal mark. A comma-separated file then lands in a single column.
What Satr does
Satr detects number formats such as 1.234,56 and 1,234.56, as well as Arabic-Indic digits, and you can override the choice in the preview. The CSV is UTF-8 with a byte order mark and can use a comma or a semicolon; the semicolon version also writes decimal commas.
If the numbers still look like text
Use the XLSX file instead of the CSV, or set the column format in Excel to Number. Check one row against the statement before summing.
Limits
Satr works with text PDFs downloaded from internet or mobile banking. It does not read scans or photos (no OCR), it uses a generic parser with no per-bank templates so you may need to set the column types yourself, and it is not affiliated with any bank. Check the result against your original statement before you use it.
Questions
Which export should I use in Europe?
XLSX is the simplest because the amounts are real numbers. For a CSV choose the semicolon option.
Can I change the detected number format?
Yes. Choose the right format in the preview if the automatic choice is wrong.
Will accented characters survive?
Yes. The CSV is UTF-8 with a BOM so Excel reads accents and non-Latin scripts correctly.
