UiPath LINQ - From Advanced to Expert

Explore the basics of Linq, learn its core functions, integrate Linq into daily tasks, including aggregations, grouping with arrays, dynamic queries, and handling exceptions, and apply Linq to your robots.

Explore UiPath Linq to filter and transform bulk data, convert excel sources to lists or csv, and apply per-row functions to produce structured results.

Retrieve excel data table values by iterating foreach row and selecting columns by name or index, then use the field method for typed results to avoid object pitfalls.

Filter rows by length and select names using length-based predicates, showing how to chain filter and select on an enumerable of data rows, handling data row types and length calculations.

Filter collections with where clauses and project data to find the maximum length of a last name using a language integrated query in UiPath linq.

Learn how to return different results in UiPath LINQ by using select to transform data rows into strings, selecting emails, and joining them with a separator.

Learn advanced uses of the select function in UiPath LINQ: filter by length, append to emails, perform length-based math, convert to double, and chain select with where to produce booleans.

Expose results from a language integrated query by chaining multiple assigns on a list of data rows, filtering by user email domain, and using for each to show matches.

Learn how language integrated queries lazily evaluate, delaying results until a forceful operation like toList runs. See how enumerable promises require explicit evaluation to avoid crashes.

Learn to simplify aggregates in UiPath LINQ by using the element selector to return only the amount column within each group while preserving the group key.

Explore count and long count in language integrated query, compare overloads, and learn to count with and without predicates, using group by and where to filter data rows.

Learn to perform group by operations in C# using new syntax with object arrays, computing sums and other aggregates by selecting fields via anonymous types, and preserving order for display.

Use select with inline functions to transform a complex object into an array of values, returning year and number by position to enable multiple values from a single query.

Define and reuse a function inside invoke code to compute min, max, and average on a data table, with configurable selectors in C# or VB.

Improve query performance in UiPath by replacing repeated contains checks with a hash set of customer IDs, enabling faster lookups across large data sources.

Learn to join two data sources in UiPath LINQ, displaying id, first name, last name, and payment amount, and compare array-of-objects joins with typed joins for readability.

Analyze whether a simple process or a framework best fits this UiPath project, weighing out-of-the-box transaction status, retry options, and exception handling without adding unnecessary framework complexity.

Learn to read large Excel files efficiently in UiPath by using an Excel application scope, reading ranges to a data table, and filtering by report type on dynamic sheet names.

Learn how to merge a source data table into a target Excel sheet by adding an amount column, copying values with a compound query, and aligning columns using UiPath LINQ.

Run a dry-run on large excel files with UiPath LINQ using excel application scope, verify the merged results, and filter to confirm five items across columns and rows.

Learn to limit variable scopes in UiPath workflows by collapsing visibility, using sequences and app scopes to improve readability and maintainability of cash and revenue reports.

Configure the solution to validate report file paths, handle file not found exceptions, and merge revenue, cache, net, and cash flow reports using path combine and directory route in UiPath.

Learn to load xml from a web url using XElement.Load, navigate to elements, and extract values, while reusing one download across queries and comparing with ui element text retrieval.

Learn to extract all XML elements from a document using the elements method to obtain an enumerable of XElement, cast to XElement, and read their values.

Learn how to gracefully handle missing elements in UiPath LINQ by using first or default, guarding with if not nothing, and assigning first elements to variables to avoid exceptions.

Learn to convert xml to a data table in UiPath by building a three-column table (publishing date, currency name, rate) using invoke code with C# to extract values.

Learn how to filter data in UiPath LINQ invoke code using a where clause to select rates whose currency starts with B, returning only the matching cube entries.

Define a namespace, apply it to all elements, save to a separate file, and refresh to verify that elements are under the specified schema.

Explore json and xml sources within a structured project, where each folder represents a section and each file a video you've watched.
