Take for example that you want to always store the first field in your JSON file, regardless of what it's named.

#POWERSHELL SEARCH MULTIPLE EXCEL FILES HOW TO#

One of the disadvantage of working with a custom object is that it is not obvious how to get the name of a property. For more complex, nested JSON fields, it is easier to assign variables to sections of the JSON object rather than using the path from the base object each time.Īt this point it helps to take advantage of the custom object's inheritance from the PsObject class. If the contents of the file is predictable, you could directly reference properties and subproperties based on known field names. Get-Content -Raw -Path $JSONFile | ConvertFrom-Jsonįrom here onwards, parsing will depend on the specifics of the JSON file. Due to this largely one to one mapping, we are also able to convert text based custom objects to JSON. Each field in the JSON file is converted to a custom object property. By default, the ConvertFrom-JSON function in Powershell converts the contents of a JSON file into a custom object. When parsing JSON using Powershell, the opposite happens. Value JSONįor the last section, I concluded on constructing custom objects in powershell for Excel files. $newObj | Add-Member -MemberType NoteProperty -Name. Then, we can add members to the object using the following function. First the object is created, like I mentioned before no properties need to be declared ahead of time. Generally, adding members to custom objects is trivial. This allows for later flexibility for what we want to do with this data. This is due to the each cell or range being a custom object, thus the Value2 is a member of the cell or range object.įor my purposes, I exported the data from these excel sheets into a powershell custom object. One of the stranger parts of this syntax is the Value2 used to access cell values. Paste Range (Requires new range selection after copy)įind last used row (Can be used to find number of rows) Some useful Excel Powershell Functions Select range of cellsĬopy range (Will return true if successful) Thus, for more custom applications, loops can still be a valuable tool. This is fairly powerful, but it can difficult to directly manipulate individual cells within a range. This allows for the value of multiple cells to be set simultaneously using familiar Excel syntax. The range property allows the specification of one or more cells. $worksheet = $(.)Īt this point we are ready to directly with the sheet, I have included some helpful parsing functions below. Marking a worksheet as active allows for the range property to be used without referencing a specific sheet beforehand.

Sheets can be selected either by index or by name. Then, a sheet should be marked as the active worksheet. Since excel files are generally made up of multiple sheets, we are require to select a specific sheet before individual cells can be parsed. Using this excel object, we can open a specific Excel workbook for parsing by passing the path string as an argument. $Excel = new-object -comobject excel.application We begin parsing Excel files by calling a custom object:

This easily allows for custom objects as outputs. In Powershell, object are made up of members: these member are functions or data structure associated with the objects.

Thanks to the integration on the Microsoft side, we do not need to download additional modules or files before working with these.įor those unfamiliar with Powershell, it plays pretty loose with it's objects, allowing you to mix and match its members without rigorous definition beforehand like in Java or Python. It allows you to access data stored across the file system, including Excel and JSON files.

The Powershell scripting language is designed to help system administrators automate tasks and manage OSs: Windows is naturally supported, but so is Linux and Mac with the newest versions.
