3279955 - CSV Export and Excel Import


Microsoft Excel interprets cells of CSV files. This could have two consequences:

  • Cells containing certain patterns (like “=2+3”) don´t show their pure content but display a calculation result (like “5”).
  • Malicious users could enter fields in ByDesign that intentionally show wrong results when exported to CSV.

The general recommendation is to adjust interpreted CSV cells, e.g. every leading “=” should be prefixed by an apostrophe (like “'=2+3”).

In ByDesign, CSV files are not only used for data display in Excel but also for general data export and import. At several places field values have direct impact of business (e.g.: the ID “=ABC” is different from the ID “'=ABC”). Tests have shown that such a modification leads to critical issues. In consequence, ByDesign cannot follow the recommendation; it leaves the data unchanged during export. (“=2+3” remains “=2+3”.)


To avoid that issues interfere with other parts of the document or exploit known vulnerabilities:

  • Follow your company policy of keeping the software (Excel or other spreadsheet applications used) up to date.
  • Recommend users to be cautious while dealing with CSV files with macros, following general best practices.
