Turning “$1,234.50” and “(45.00)” into numbers
Currency symbols, thousands separators, accounting negatives, percentages and the decimal comma.
Numbers exported from accounting tools, shops and banks are formatted for people, not for formulas. A cell that shows $1,234.50 is text to most tools, so sums ignore it and sorting puts $9 after $10.
What the number step removes
- Currency symbols and codes:
$ € £ ¥ ₹,USD,EURand others. - Thousands separators: commas, apostrophes (
1'234.50) and spaces, including the non-breaking spaces French and German exports use. - Accounting negatives:
(45.00)and the trailing minus45.00-both become-45.00.
Grouping is checked strictly: 1,5 is not read as 15 or as 1.5 unless you say the file uses a decimal comma. Values that cannot be read are left unchanged and counted in a warning, so nothing becomes a wrong number silently.
Decimal comma files
Much of Europe writes one thousand two hundred and thirty-four point five as 1.234,5. Tick Input uses a decimal comma and the step reads it correctly. Output always uses a decimal point, which is what databases and most software expect.
Percentages
Choose whether 12.5% stays as it is, becomes 12.5, or becomes the fraction 0.125 (what spreadsheet formulas use).
Rounding
With Decimals set, values are rounded half away from zero on the digits themselves, not through floating point, so 1.005 becomes 1.01 and long IDs are never altered. Leave it at Keep as written to only strip formatting.
Leave IDs alone
ZIP codes, phone numbers and account numbers look numeric but are identifiers: 02134 must keep its leading zero. The cleaner only suggests columns that carry formatting such as currency symbols and never suggests columns with leading zeros. When you download XLSX, values with leading zeros stay text.
