For example, you can add them to ArcMap, preview them in ArcCatalog, and use them as inputs to geoprocessing tools. Excel files are added to ArcMap in the same way as other data, through the Add Data dialog box.
When you browse to an Excel file, you will need to choose which table you want to open. Worksheets or named ranges with names containing spaces have single quotation marks placed around the table name.
Once added to ArcMap, you can open the table from the Source view of the table of contents. However, you will not be able to edit the table or export records to an Excel format.
The following example contrasts how a multisheet document is exposed in Microsoft Excel and on the ArcMap Add Data dialog box. When working with Microsoft Office Excel files, keep the following in mind:.

Excel does not enforce field types for values during data entry as standard databases do. Therefore, the field type specified in Excel is not used in determining the field type exposed in ArcGIS.
Instead, field type in ArcGIS is determined by a scan of the values in the first eight rows for that field. If the scan finds mixed data types in a single field, that field will be returned as a string field, and the values will be converted to strings.
Numeric fields are converted to the double data type in ArcGIS. Excel tables behave in the same way as other tables that don't have an ObjectID field. This means you will be unable to edit, perform relates, or make selections on the map.

ArcGIS Enterprise. ArcGIS Online. Not applicable.ArcGIS Blog. This blog entry contains links to a table with guidelines for how to format your Excel table, as well as a couple of other useful related resources. View the table with the guidelines. The guidelines include references to special characters you cannot use when naming fields in ArcGIS and reserved words you cannot use when naming fields in Excel.
The guidelines are for the use of geodatabases and feature classes, not shapefiles. When using shapefiles, additional dbase-based restrictions will apply, such as limiting field names to 10 characters. View the list of Excel Reserved Words. Note that the Excel reserved words were extracted from the driver via ArcObjects.
We have a function that returns the Keywords for a data source. In the case of Excel, it gets the list from the driver itself. Thanks to Veronica Rojas for helping me to test the various issues.

The first two of these three cases were tested and are reported on here. All rows in a table have the same columns. In a spatial table, columns store categories of information about the features, such as names, ID numbers, and area or length. In a spatial table, each row represents one feature. One advantage of Excel is that it allows much larger worksheets 1, rows by 16, columns than you can have in Excel 65, rows by columns.

Previous ArcUser articles described the benefits and limitations of spreadsheets in the version of ArcGIS current at that time. Since these articles were published, Microsoft has released two new versions, Excel and Excel With each release, spreadsheet capabilities have improved and the processes for importing data into ArcGIS have changed.
Although the sample data is synthetic, it is true to the underlying geology of Battle Mountain, Nevada. The tutorial uses spreadsheets to create and enhance geologic data.
In this exercise, we will model a well-known gold and base metals mining area in northern Nevada, located near the town of Battle Mountain. The custom samples are typical of data that might come from the field, assayed by a modern analytic laboratory.
If you have installed Officeyou can read. If you have Office or installed, you can read. If you do not have Microsoft Excel installed, you must install the driver before you can use either. Carefully follow the installation instructions before you restart ArcGIS. To begin this exercise, download the training data. Unzip the excelmagic. Inside this folder, expand all files. Scroll down through the table and observe that many fields in the right-aligned columns are empty.
In the source CSV file, many of the fields contain nonnumeric strings that do not display properly. When a geochemical lab is unable to measure the presence of an element, the analytic posting will include a less than character, followed by the detection limit value.
If those first eight rows contain mixed data types in a single field, that field will be converted to a string field, and the values contained in that field will be converted to strings. Consequently, some rather detailed data preparation will be necessary before you can use these files. Close ArcCatalog. These detailed instructions are specifically for Excel and Excel This data is often used as part of a regional reconnaissance program.
Prepare the HSSR data for import. Now to prepare the Rock and Soil analytic data for proper import—a much more difficult task. Instead, change them to a smaller absolute value, typically 20 to 50 percent of the detection limit. Take a more conservative approach and use 20 percent. When the same file is viewed in WordPad, blank fields contain values preceded by a symbol.
These indicate values below the detection limits and will be replaced using values in Table 1. This approach is much more powerful, but also dangerous. The danger with using Excel to edit and format analytic data lies in how it uses leading zeros to manage alphanumeric strings when all other characters are numeric. Excel tends to convert leading zero strings to numeric values, which forever changes the data.Cake mercotte
This can be especially dangerous when working with datasets such as tax parcels and lab samples. However, if the file is saved from Excel back into a CSV file, the leading zeros are gone forever and there are no problems.
Once all tables have been carefully prepared, they are imported into a new file geodatabase called Geochemistry.ArcGIS Blog. In the age of databases and cloud based data storage, many organizations still maintain valuable data in Microsoft Excel and comma-separated value CSV files.
It consists of fictitious sample data, that is true to the underlying geology. Landownership information is imaginary,but reflects exploration trends around Battle Mountain, Nevada, in the early s.Terminal block
The Rock worksheet contains sample numbers, coordinates, and field information that will allow this data to be displayed on a map. Similar to the Rock worksheet, the Soil worksheet also contains sample numbers, coordinates, and field information. Both CSV files were obtained from an assay laboratory and contain results of chemical analysis of rock and soil samples taken at locations in the Battle Mountain area.
Values in the tables represent trace elements used in gold exploration and are indicator minerals used to assess the potential for finding viable gold deposits. Left alignment generally denotes that a column contain text strings and not numbers that may be used to determine values greater than a specific range.
Right alignment identifies a column as containing numeric values. Consequently, for many worksheets, some data preparation is necessary to ensure the data is correctly identified in ArcGIS Pro. Before making updates to the worksheet, lets make a copy of the workbook so you can retain the original data as an archive. In addition, many samples are coded by Claim Group. Notice that several column names contain spaces.
Recall that field names must contain only letters, numbers, and underscores. In the Rock worksheet, review the first row of data containing column names, and then update names by replacing spaces with underscores. Next, you will edit and format the companion laboratory assay data for the Rock and Soil worksheets. These records each contain less than the minimum detectable amount of a specific element. The over-limit samples in this dataset have already been resolved, so only the less than values need fixing.
Use Find and Replace to change all additional values below the detection limit for arsenic, gold, mercury, silver and antimony with values shown in table below.
The Format Cells pane displays.
Notice that the field is currently categorized as General. In the Format Cells pane, click Number to change the field category. Change Decimal places to 0and then click OK.
Formatting an Excel table for use in ArcGIS
You have completed data preparation of the battle mountain data currently stored and maintained in Excel and CSV files. Microsoft Office Excel tables may be used directly in ArcGIS Pro and you can work with them in the same way as other tabular data sources. For example, you can add them to the map, open them in the fields view, and use them as inputs to geoprocessing tools. Please verify the Microsoft Access Database Engine is successfully installed and operational before continuing.
The tool creates a new feature class named RockSampleLocations in the project geodatabase and adds the feature class as a layer to the map displaying rock sample location points in the Battle Mountain Nevada region. The layer attribute table displays. Note the layer field names derived from the original column names in the excel table.
Notice the field data types, these types are the same as the categories you assigned to columns in Excel. Review the RockSampleLocations attribute table. Scroll to the right to display the joined fields.Importing CSV Text Files with XY Data into ArcGIS Pro
In the Symbology pane, for Primary symbologychoose Graduated Colors. The map updates to display rock sample locations with graduated colors representing parts per billion of gold detected in samples. Review the map and note the location of several samples displaying a high value for gold.
Congratulations, you have now successfully imported several Excel tables to generate new geodatabase feature classes and joined assay data to the points for visualization. Before coming to Esri inhe was an Esri software instructor for the Esri distributor in South Africa.For example, you can add them to the map, open them in the fields view, and use them as inputs to geoprocessing tools.
If you attempt to access an Excel file in ArcGIS Pro without the appropriate driver installed, you will receive the error Required Microsoft driver is not installed. If you try to install the downloaded AccessDatabaseEngine. To work around this problem, you will need to perform a silent installation of the downloaded file by doing the following:.
You add Excel files to a project in the same way as other data: click the Add Data button on the Map tab. When you browse to an Excel file, you must choose the table you want to open.
Worksheets with names containing spaces will have the spaces replaced by underscores. Once the table is added to the map, you can open it in the Contents pane. However, you cannot edit the table or export records to an Excel format. The following example contrasts how a multisheet document is exposed in Microsoft Excel and on the Add Data dialog box:. Follow these best practices for field naming, particularly if you want to join an Excel table to another table: Field names must start with a letter.
Field names must contain only letters, numbers, and underscores. Field names must not exceed 64 characters. You add Excel files to a project in the same way as other data: click the Add Data button on the Map tab, or use the Catalog pane. When working with Microsoft Office Excel files, keep the following in mind:.
If you make edits to a worksheet outside of ArcGIS Pro while it is open in the Contents pane, and then try to remove and re-add the layer without restarting ArcGIS Pro first, you may receive an unsupported data type error. When an Excel worksheet is added to a map, ArcGIS Pro will attempt to maintain all characters present in the sheet or field name and display this in the stand-alone table.
When used in a geoprocessing tool, the underlying table is used directly, so you may notice a slight change in the name. Note: If the table name does not contain an expected character, it may have been replaced by the Microsoft driver before ArcGIS Pro accessed it. This is known to occur for a small subset of characters in which.!Instructions provided explain how to format a table in Microsoft Excel for use in ArcMap. Note: For instructions on formatting a table in Excel to be used directly in ArcMap 9.
Column headings require the following: must contain only letters, numbers and underscores must start with a letter must not exceed ten characters must be formatted as text Note: For more information about formatting field and table names, see "What characters should not be used in ArcGIS for field names and table names?
Expand all the columns in the table, so the values in the columns are visible. If columns are not expanded, the values will be truncated to 10 characters. Delete extra sheets. Select all the cells in the populated rows and columns in the table, including the field headings. Select a supported format from the choices available in Excel and click Yes when Excel warns that certain formatting is not supported in this file format.
