Limits and things to check
100% Client-side conversion. Financial records and personal accounting data never leave your device. Supports CSV, TSV and custom comma or tab delimiters up to 40 MB.
Before you start
- Check the delimiter and encoding of exports from banks or accounting systems; semicolon files and non-UTF-8 files are the usual cause of everything landing in one column.
- Watch columns with leading zeros, long account numbers and dates, which spreadsheets can reformat if they are treated as numbers.
- Remove columns you do not need before sharing the workbook with an accountant or colleague.

Can I leave out columns?
Yes. Headers are detected and you choose which columns go into the workbook, with a preview before export.
My file uses tabs or another separator. Will it work?
Yes. CSV and TSV are supported, with comma or tab delimiters, up to 40 MB.
Why do some numbers look different in Excel?
Excel applies its own formatting to long numbers, dates and leading zeros. Compare a few rows with the source before you rely on the workbook.
