Source Format Guide

What is Microsoft Excel 97-2003?

XLS is the legacy Microsoft Excel binary workbook format (Excel 97-2003) and still shows up in geospatial workflows whenever long-running inventories, government records, or older business exports predate the modern XLSX standard.

XLS workbooks carry tabular records in a proprietary binary structure, so they are read through dedicated parsers rather than the zip-and-XML approach used for XLSX.

Like any spreadsheet, an XLS file becomes spatially useful only when its sheets include coordinate columns or fields that a GIS tool can interpret as location data.

Common Workflows

Common use cases

Asset registers, monitoring logs, and address lists accumulated in older Excel versions.
One-off conversions of historical business data into mappable point layers.
Replacing fragile .xls attachments in reporting pipelines with GIS-native outputs.

Ecosystem

Where you will encounter it

Legacy office and reporting workflows that predate the OOXML standard.
Government and enterprise archives that standardized on Excel 97-2003 exports.
Migration projects moving archived spreadsheets into GIS databases.

Strengths

Why teams choose Microsoft Excel 97-2003

Universally readable by Excel itself and by modern parsing libraries, so legacy archives remain accessible.
Familiar to every business audience, with no GIS software needed to review the rows.
A single-file container keeps sheets together when moving archived data.

Limitations

Where Microsoft Excel 97-2003 gets awkward

The binary BIFF structure is not human-readable and does not model geometry, CRS, or spatial metadata.
Excel 97-2003 limits sheets to 65,536 rows, which constrains larger exports.
Writing XLS is deprecated across modern tooling; XLSX is the preferred output for round-trips.

Conversion steps

How to convert Microsoft Excel 97-2003 to MapInfo TAB online

File Structure

Common file extensions and sidecar files

.xls

Legacy Excel 97-2003 binary workbook that can contain one or more sheets of tabular data.

coordinate columns

Latitude, longitude, easting, northing, or similar fields that let GIS tools interpret spreadsheet rows spatially.

multiple sheets

Workbook structure that may separate tabs by theme, status, or export purpose.

Conversion Rationale

Why convert Microsoft Excel 97-2003 to MapInfo?

Teams commonly convert Microsoft Excel 97-2003 into MapInfo when they need compatibility with MapInfo Pro and business mapping environments.

Teams convert XLS when archived spreadsheet records need to become proper geometries in a map-ready format.
They move away from XLS toward XLSX or GeoPackage when the working pipeline needs a sustainable, non-deprecated container.
MapInfo TAB remains common in organizations with established MapInfo desktop workflows.
Exporting to MapInfo is useful when recipients expect TAB datasets and associated sidecar files.

FAQ

Frequently asked questions about Microsoft Excel 97-2003

What is the difference between XLS and XLSX?

XLS is the Excel 97-2003 binary format (BIFF inside an OLE2 container), while XLSX is the modern zip-and-XML standard introduced with Office 2007. Both hold tabular data, but XLSX is the safer choice for new workflows.

Can I still open legacy .xls files?

Yes. Modern parsing libraries read BIFF workbooks directly in the browser, so legacy files stay accessible without installing Excel first.

Why convert XLS into GeoJSON or GeoPackage?

Those targets turn spreadsheet rows into explicit spatial features that can be previewed, styled, and analyzed on a map.
