CSV to Excel, explained
Turn a .csv or .tsv export into a proper .xlsx: the first row becomes a frozen header with filters, numbers are stored as numbers and the columns are sized to fit.
What is converted, and how
- Header row
- The first line, in bold on a blue fill, frozen while you scroll and with filters on.
- Numbers
- Plain numbers such as
42or-3.5become numbers you can calculate with. - Leading zeros
- Values such as
0042or postcodes stay text, so the zeros are kept. - Formulas
- Cells that start with
=,+,-or@are stored as text, so a CSV can't slip a formula into your workbook. - TSV
- Tab-separated files work the same way: open a .tsv or choose TSV under From.
Limitations
- Fields must be separated by commas (CSV) or tabs (TSV). Files that use semicolons, as Excel does in some countries, end up in a single column.
- The file must be UTF-8. Numbers with thousands separators, currency or percent signs, and dates stay text.
- Up to 512 KB.
Tips
- Need the data in a report instead? A CSV converts to a Word table, a PDF or a Markdown table too.
- The file is converted in an isolated, temporary workspace on our server and deleted as soon as the result has been sent back. It is never stored or logged.
