Convert E00 to TAB Online - Free & Fast

What is E00?

ArcInfo Exchange (E00) is a proprietary interchange format developed by ESRI for exporting and importing Arc/Info coverages, encoding vector topology, attributes, and raster data in an ASCII text file for data migration between GIS systems.

What is TAB?

MapInfo TAB is the native read/write format for MapInfo Professional, storing vector layers with geometry, attributes, styling rules, and projection information in a set of files that together form a complete map layer.

When Should You Use E00 vs TAB?

E00 vs TAB: Key Differences

• •E00 and TAB diverge on compression: lossy compression for the source, lossless compression for the target.
• •Converting from E00 to TAB changes compression type: lossless source becomes larger but with full quality preservation.
• •How transparency is handled: TAB supports transparency, so alpha information is preserved during conversion.
• •Storage footprint: 100KB to several GB depending on coverage complexity for E00 vs 10KB to 2GB depending on layer complexity for TAB.
• •Use case fit: E00 targets legacy arcinfo data migration, gis archival data recovery and TAB targets mapinfo gis projects, cadastral mapping, desktop spatial analysis — your choice depends on which workflow stage you are serving.

Advantages of E00

• ✓E00 compresses data using lossy methods, keeping file sizes manageable for Legacy ArcInfo data migration, GIS archival data recovery.
• ✓Industry-wide support means E00 files open anywhere — from legacy systems to the latest devices.
• ✓Small file sizes make E00 ideal for email, web uploads, and cloud storage.
• ✓From professional software to open-source alternatives, E00 works out of the box.

Advantages of TAB

• ✓TAB applies lossless compression specifically calibrated for MapInfo GIS projects, cadastral mapping, desktop spatial analysis.
• ✓TAB enjoys broad native support across operating systems, browsers, and creative tools alike.
• ✓TAB guarantees every bit of the original data survives — no approximations, no shortcuts.
• ✓You will find TAB support built into virtually every tool that handles MapInfo GIS projects, cadastral mapping, desktop spatial analysis — no plugins or converters needed.

Common Use Cases for E00 to TAB Conversion

Industry Applications

Best Practices for E00 to TAB Conversion

• →When converting E00 to TAB: confirm the coordinate reference system (CRS / projection) is preserved or explicitly reprojected
• →Keep attribute tables and feature metadata intact — TAB should retain all fields from E00
• →Check geometry types (point, line, polygon) map cleanly between the two formats
• →Verify that z/elevation values and topology survive the conversion when working with terrain data
• →Always keep a backup of your original files before converting
• →Choose the appropriate quality settings for your specific use case

Troubleshooting E00 to TAB Conversion

• !Topology errors in the converted TAB → self-intersecting polygons or duplicate vertices may not transfer cleanly between formats
• !The TAB file coordinate values shifted slightly → datums (WGS84 vs NAD83) differ even when the projection looks similar
• !Time field values were corrupted after converting E00 to TAB → date and time field formatting varies across GIS formats
• !Null geometry features appear in the converted TAB → empty or null-shape records in E00 may cause validation errors in some formats
