How It Works
1
Drop your Excel fileDrag and drop any
.xlsx or .xls spreadsheet onto the tool, or click Browse to pick one. Multi-sheet workbooks are supported — choose which sheet to export.2
Automatic type detection & conversionThe converter reads each column and infers the best DBF field type:
N for numeric columns, D for dates, L for boolean, and C for everything else. Field names are sanitised to the 10-character dBASE limit.3
Download your .dbf file instantlyA standards-compliant dBASE III+ binary file is assembled in memory and offered for download — ready to open in ArcGIS, FoxPro, QGIS, or any legacy database tool.
What Gets Converted
- Text / Character fields — Any column whose values cannot be classified as numeric, date, or boolean is written as a
C(Character) field, up to 254 characters wide. - Numeric fields — Integer and decimal columns are written as
Nfields. Decimal precision is inferred from the widest value in the column (max 15 decimal places). - Date fields — Excel date serial values are converted to dBASE
Dfields stored asYYYYMMDDstrings. - Boolean / Logical fields — Cells containing TRUE/FALSE or Yes/No become
L(Logical) fields stored asTorF. - Field name sanitisation — Column headers are trimmed to 10 characters, illegal characters replaced with underscores, and duplicate names de-duplicated automatically.
- Empty row skipping — Rows where every cell is blank are omitted by default, keeping your DBF clean and compact.
