Formulas, pivot tables and charts

Everything you expect from a spreadsheet is here: math, statistical, financial, logical, text, date and lookup functions (including SUM, IF, VLOOKUP and SUMIFS), pivot tables to summarise big data sets in seconds, and column, line and pie charts that update live. Conditional formatting and data validation keep your data clean.

Correct Arabic numbers, dates and AED currency

Xrero Calc renders numerals, currency (AED) and Hijri/Gregorian dates correctly in both English and Arabic — perfect for UAE VAT sheets, invoices, budgets and price lists. Open a colleague’s .xlsx, edit it, and save it back so nothing is lost.

It also reads .xls, .ods and .csv, and exports to PDF.

Free, offline, and built to help everyone

Xrero Office exists for one reason: everyone should be able to open, edit and share documents without paying for a subscription. It is 100% free, it runs offline on your own Windows PC, and it treats Arabic and right-to-left as a first language. There is no trial, no credit card and no paywall — just download it, create a free account once, and start working.
