A spreadsheet with unique capabilities for processing big data sets. You can edit large CSV files with millions of rows, XLSX files that are automatically split and merged, build complex data models e.g. with millions of look-up formulas that are opened/updated almost instantly and clean, transform, publish multi-gigabyte data sets.

* 32 million rows x 16,384 columns - the number of worksheets and subfolders is unlimited. No limit for the file size (4GB+). Large text, CSV files exceeding the 32M/16K limits are automatically split into multiple sheets and saved (then load/read/edited) together in one zip.

* Up to 500GB of data per worksheet.

* Pivot tables with 256 million rows and numerous data functions (e.g. 2x more than in Excel).

* Monte Carlo Simulations to easily estimate risk in business, costs, future pensions or simply to reverse-calculate formulas etc.

* Charts easily handling millions of data points.

* Fastest lookup functions using binary algorithms.

* Up to 64 cores used when updating worksheets and pivot tables.

* Around 450 built-in functions, solver functions with no strict limits of variables.

* All functions can access data from any number of closed workbooks.

* All functions can be redefined/rewritten by a user, and you can add any number of new functions (having the same properties as the built-in ones: automatic full multicore calculation support, "spilling"/array usage etc.).

One-time fee payment ($19.50), no subscriptions. Free new versions for 12 months. GS-Calc can be installed on any portable storage device and used without performing any registry modifications. No internet connection needed. Not tied to your hardware.

Sample videos:
  • Using a 2.37GB workbook with i5, 16GB RAM & HDD: 32 million formulas and 300 million random number/text cells.
  • Using the FILTER() function to filter 3.3 million rows.
  • Creating a script in GS-Calc to mass-import tables from CSV/text/xBase/xlsx files
  • Using MonteCarlo simulations to find sets of 100 numbers that add up to a give value.
  • MonteCarlo simulations in GS-Calc to find linear programming solutions.
  • 12 million fast binary VLOOKUP's in GS-Calc.

GS-Base is a database that lets you store any type of data: text and numeric fields, dates, long text memo fields, files, images, code snippets with syntax highlighting for 16 programming languages.

GS-Base can be useful for both simple applications like organizing your photo collections and extracting any EXIF tags from photos to find photo duplicates or similar photos, playing filtered/random mp3 files, or listing all your disk files, monitoring file changes and adding any type of metadata to files, to clean data, transform using regex, analyze multi-GB data sets with up to 256 million rows.

You can perform both simple and complex record filtering, searching for duplicates, for unique values and frequencies, full-text searches, find-as-you-type, fuzzy searches, searching quartiles, random searches and one-click statistical breakdown analysis. You can use unlimited in-cell charts to spot trends.

You can also analyze very large data sets using pivot tables with up to 256 million rows and 16,384 columns. You can use around 300 built-in calculation function in calculated fields, for data validation, cleaning and conversion. GS-Base can use from 1 to 100 processor cores when updating calculated fields and pivot tables (e.g. Excel: 11 data functions, 1 million rows; GS-Base: 25 functions, 256 million rows, full regex filtering).

GS-Base can filter text/CSV files of any size regardless of the installed RAM. With GS-Base things like performing tables joins, normalizing (splitting) tables, merging records are easy and fast, even for millions of records.

GS-Base can be installed on any portable storage device and used without performing any registry modifications. It requires around 10MB of free space and it's fully offline - no internet connection needed.

GS-Calc is a full featured spreadsheet that can be used for editing huge files and to build complex data models with millions of formulas and GBs of data.
Worksheets and pivot tables can use 12 million rows. No limitations for using cell references to external closed workbooks.
No limitations for the number of hyperlinks. Users can add their own DLL libraries with new functions or functions replacing the default ones, with the same performance, dynamic array ("spilling") functionality and multi-core calculations. Extensive use of regular expressions in the built-in functions (Filter(), Find(), lookups) and Find&Replace functions. Automatic use of binary searching in lookup functions with any number of ranges sorted in the background.

Opening an over 4GB workbook with over 500 million cells with random floating-point numbers and text strings (8 worksheets, ~12 million rows each) should take around 30s on a low-end office pc with 16GB RAM.
Filtering (regex/operators/formulas/duplicates) a few million rows should take a few seconds (and the result can include millions of rows as well).
GS-Calc can be installed on any portable storage device and used without performing any registry modifications.

GS-Base - a database with spreadsheet functions and up to 256 million rows.
Pivot tables (with the same max number of rows), around 300 functions in calculated fields. Filtering (regex), searching for duplicates, for unique values, search-as-you-type, full-text searches, fuzzy searches and so on. GS-Base uses up to 100 processor cores to perform field and pivot table calculations.
Opening an over 0.5GB csv text file with 20 columns and around 3.5 million rows can take several seconds on a low end pc. Loading about 12GB MySql *.sql file with over 10 million records and Long Text (Memo) fields can take around 2 minutes. Filling a field in a 150 million record set with some 1...n sequence will take a few seconds. Same as filtering a field using regular expressions. 150 million records with four text field containing up to several characters each with calculated fields and formulas can use around 15GB of RAM.
